Answer:

B 144

Step-by-step explanation:

In Math, the exclamation mark is called factorial. The factorial of a number n is the product of all integers less than or equal to n but greater than or equal to 1. For example, the factorial of 5 is 5! = 54321

With this, 4! = 4321 and 3! = 321

Therefore, 4!3! = 4! 3! = 4321321 = 144
