A broker-dealer must safeguard customer funds and securities by segregating customer assets from the firm's proprietary business activities. Segregation helps ensure that customer securities and cash are not improperly used by the broker-dealer and remain available for customers, even if the firm experiences financial or operational difficulty. Choice D is correct. FDIC insurance applies to bank deposits at insured depository institutions, not brokerage securities accounts. Brokerage customer protection is generally associated with customer protection rules and SIPC coverage, not FDIC protection. Choice B is prohibited because firm personnel may not sign on behalf of customers merely for convenience. Choice C is incorrect because broker- dealers do not protect customers from market losses caused by declining securities values. The safeguard concerns custody and proper handling of customer assets, not investment performance. The SIE outline includes customer protection and custody of assets, improper use of customer securities or funds, and books and records requirements. It also lists FINRA Rule 2150, improper use of customers' securities or funds, and customer protection-related rules. Reference: Section 3.2.4 Books and Records and Privacy Requirements; Section 3.3.3 Other Prohibited Activities.

An option is considered "at the money" when the current price of the underlying asset (or index level) equals the option's strike price.
* B is correct because the index level equals the strike price.
* A is incorrect because "in the money" requires the option to have intrinsic value (e.g., for a call, the index level must be above the strike price).
* C is incorrect because "out of the money" applies when the index level is below the strike price (for calls) or above it (for puts).
* D is incorrect because "at the money" options have no intrinsic value.

An introducing broker-dealer generally accepts customer orders and introduces those transactions to a clearing firm for processing, custody, clearance, settlement, and recordkeeping functions. Choice C is correct.
Introducing firms commonly maintain the customer relationship, solicit and accept orders, make recommendations, and provide front-office brokerage services. They typically do not carry customer accounts, custody customer funds or securities, or directly clear trades with clearing agencies. Choice A describes a clearing function, not the usual role of an introducing firm. Choice B is generally performed by the carrying or clearing broker-dealer that holds customer assets. Choice D is also generally associated with the carrying broker-dealer, which prepares and sends official account statements and confirmations, although introducing firms may provide supplemental communications. The SIE outline identifies broker-dealers, including introducing, clearing, and prime brokers, under market participants and their roles. The exam distinction is operational: introducing broker-dealers interact with customers and accept orders, while clearing broker-dealers handle custody, clearance, settlement, statements, and back-office processing.
