D.

10^Q = (2^Q)*(5^Q).

From stmt1: P has maximum 5 2s. Hence, P can be expressed as 2^5 * x where x does not have 2 as the factor.
Hence, 2^5 * x = (2^Q)*(5^Q) and clearly, Q will be 5. Hence, sufficient.

From stmt2: P = 5^6 * y where y does not have 5 as a factor.
Hence, 5^6 * y = (2^Q)*(5^Q) and clearly, Q will be 6. Hence, sufficient.
