By simple logic, none of those.

$\dfrac{3\times10^{20} }{ 4\times10^5}$

The number on the top is larger than on the bottom, so it will be a larger than 1 result.  It is division, so the size of the answer will be smaller than the size of the top number.

A.2.7x10^32 is larger than the top, so not the answer.

B.2.7x10^-13, C.2.7x10^-12, and D.2.7x10^-11 are smaller than 1, so not the answer.
