The question asks for the largest prime number that is less than 100.

Let's evaluate the options:

• 91: This is not a prime number since it can be divided by 7 (91 = 7 × 13).
• 93: This is not a prime number since it can be divided by 3 (93 = 3 × 31).
• 97: This is a prime number because it has no divisors other than 1 and itself.
• 99: This is not a prime number since it can be divided by 3 (99 = 3 × 33).

The correct answer is (C) 97, as it is the largest prime number less than 100.
