Answer :
The correct answer is 24
You have to apply factorials here and formulas. You have 4 letters which means that your n=4, and you have 3 objects at a time which, means that you have 4 different groups of combinations with 6 permutations in each due to the 3! factorial. 6 x 4 is 24.

Answer:
Option A. 24
Step-by-step explanation:
There are four letters a, b, c, d and we have to tell the permutations made when taken 3 at a time.
This phenomenon exist = [tex]^{4}P_{3}[/tex] = [tex]\frac{4!}{(4-3)!}[/tex]
= [tex]\frac{4!}{1!}[/tex] = 4! = 4 × 3 × 2× 1 = 24
Therefore, option (A) 24 are the permutations exist.
