Outsourcing can lead to a loss of control over certain aspects of a project, as the organization relies on external parties to deliver services or products. Additionally, sharing sensitive information with third-party vendors increases the risk of data breaches or loss of private information. While there may be concerns about assets or future business opportunities, the primary risks in outsourcingrelate to control and information security.

Strategic sourcing is for high value, high risk items. The other options given are tactical sourcing as they are low value (eggs, paper and plastic cups).
See p.3 for the differences between tactical and strategic sourcing

Cleaning and Facilities Management are the most appropriate items to outsource. They would not outsource the making of confectionary products as this is the 'core' business.

Capacity and compatibility are critical factors in supplier appraisal. Evaluating these factors ensures that the supplier can meet the buyer's requirements in terms of production capacity and aligns with responsible sourcing by ensuring the supplier's values and practices are compatible with the buyer's expectations.

Multiple sourcing is most effective for strategically important, high-value requirements such as raw materials.
These are continuous, large-volume needs where supply disruptions can be costly and damaging. By using more than one supplier, buyers reduce dependency risks, improve resilience, and increase competitive leverage. One-off requirements like machinery (A) don't benefit from multiple sourcing, while options B and D describe disadvantages rather than reasons for adopting the approach. Responsible sourcing promotes balancing cost, risk, and resilience - and multiple sourcing is a key strategy for critical, ongoing supply categories.
