Answer:

d. 20

Explanation:

The given question implies 5 permutation 2, i.e
image
image.

But,


image
image =
image

So that for
image
image, n = 5 and r = 2.


image
image =
image

=
image

=
image

Cancel out 3 and 2 with respect to the numerator and denominator.


image
image = 5 * 4

= 20

Therefore,


image
image = 20

So that the correct option is D.
