12*11*10= 1320

Ans C

I feel it is a straightforward question of selecting 3 people out of 12.

Choose 3 people out of 12 and arrange these 3 people between themselves.

12!/(3!x9!)x3!=12x11x10x9!/(3!x9!)x3!=12x11x10=1320

First person can be selected in 12C1 ways= 12 ways
second person can be selected in 11C1 ways = 11 ways
third person can be selected in 10C1 ways = 10 ways

total ways = 12*11*10 = 1320 ways
correct answer - C
