Not much sure....
But if it is red....then the number of cases when 'n' identical balls of same color (here red) is picked is 1....
On the contrary,
the number of ways of selecting n identical balls of same color is 6nCn..... So here i don't think any such integer n will satisfy this eqn, as we have 16(6n-1)(6n-2)....5n=16.

Just to mention, FIITJEE's answer to this qsn is wrong.
