C

n male and n female candidates have been recommended.
n/2 male and n/2 female candidates has to be selected from this lot.

using nCr formula we get

nC(n/2) * nC(n/2)

n! / (.5n)!(n-.5n)! * n! / (.5n)!(n-.5n)!

I guess B. I think C is wrong, in addition it was the answer last week.

I don't have any logic since this problem is to complicated.

But I think C is wrong cuz you can't pair the events together.

Yes it's B, using Pluggin IN Method

We can state that there is 4 offices,

That there is 2 men and 2 women

Combination 4,2 = 6

Using Choice B.

4! 4 x 3 x 2 x 1= 24

.5(4) =2 squared =4

24/4=6

so it's B.

Nikerun,
