There are only two prime numbers between 43 and 50, inclusive; which are 43 and 47. Thus, the product of those two prime numbers is:

43 x 47 = 2,021

Prime numbers between 43 and 50, inclusive: 43 and 47

It is not necessary further calculations, since 3x7 = 21.

Only option D has a number that units digit is 1.

The only prime numbers in the given interval are 43 and 47. Their product is:

43 x 47 = 2,021

We actually don’t have to multiply the numbers; we know the product of 43 and 47 has a units digit of 1, and the only answer choice with a units digit of 1 is D (50! and 40! both have their units digit equal to 0 and thus, the units digit of 50! - 40! is also 0).
