Step-by-step explanation:

The student has asked for the result of 5 factorial (5!). A factorial of a number is the product of all positive integers from 1 to that number.

To calculate 5!, you multiply the integers from 1 up to 5:

5! = 20 × 3 × 2 × 1

5! = 60 × 2 × 1

5! = 120

Therefore, the result of 5! is 120, making option a) the correct answer.
