Answer:

C.

Step-by-step explanation:

The  coefficients of the expansion of (a + b)^2 are 1 2 1, which is the third row of Pascal's triangle.

For (a + b)^3 they are 1 3 3 1 which is in the 4th row, and so on

So those for the (a + b)^n are in the (n + 1)th row.

C the coefficients in the expansion (a+b) are given by the (n+1) row of Pascia’s triangle.
