Explanation/Reference:
When a biometric system is used for access control, the most important error is the false accept or false acceptance rate, or Type II error, where the system would accept an impostor.
A Type I error is known as the false reject or false rejection rate and is not as important in the security context as a type II error rate. A type one is when a valid company employee is rejected by the system and he cannot get access even thou it is a valid user.
The Crossover Error Rate (CER) is the point at which the false rejection rate equals the false acceptance rate if your would create a graph of Type I and Type II errors. The lower the CER the better the device would be.
The Combined Error Rate is a distracter and does not exist.

The advantages of SSO include having the ability to use stronger passwords,
easier administration as far as changing or deleting the passwords, minimize the risks of
orphan accounts, and requiring less time to access resources.

Explanation/Reference:
Named after its inventors Ron Rivest , Adi Shamir and Leonard Adleman is based on the difficulty of factoring large prime numbers.
Factoring a number means representing it as the product of prime numbers. Prime numbers, such as 2, 3,
5, 7, 11, and 13, are those numbers that are not evenly divisible by any smaller number, except 1. A non- prime, or composite number, can be written as the product of smaller primes, known as its prime factors.
665, for example is the product of the primes 5, 7, and 19. A number is said to be factored when all of its prime factors are identified. As the size of the number increases, the difficulty of factoring increases rapidly.
The other answers are incorrect because:
El Gamal is based on the discrete logarithms in a finite field.
Elliptic Curve Cryptosystems (ECCs) computes discrete logarithms of elliptic curves.
International Data Encryption Algorithm (IDEA) is a block cipher and operates on 64 bit blocks of data and is a SYMMETRIC algorithm.

Which means the company understands the level of risk it is faced.
The following answers are incorrect because :
Reject the risk is incorrect as it means ignoring the risk which is dangerous.
Perform another risk analysis is also incorrect as the existing risk analysis has already
shown the results.
Reduce the risk is incorrect is applicable after implementing the countermeasures.
