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! = 5 × 4 × 3 × 2 × 1
5! = 20 × 3 × 2 × 1
5! = 60 × 2 × 1
5! = 120
Therefore, the result of 5! is 120, making option a) the correct answer.
