Given:

The function is

To find:

The zeros of the given function.

Solution:

The general form of polynomial is

      ...(i)

where, a is a constant, are zeros of respective multiplicities .

We have,

On comparing this with (i), we get

It means, -3 is a zero with multiplicity 2 and 5 is a zero with multiplicity 6.

Therefore, the correct option is B.
