I think it should be D.
1> 10C6 will give all possible combinations of distributing 6 scholarships among 10 people but we dont know which of these are valid as per the clause "one person can get only one type of scholarship". So we cant find the right number of combinations.

2> here we dont know how many scholarships will be granted.

Taking 1 and 2, we know that the only possible combination is 2,2,2.
What is OA?

i think you mean C

combinations can be like this 10C2+ 8C2+6C2
