Let \( X=\{1,2, \ldots ., 10\} \), if set \( A \) and \( B \) are formed from elements of \( X \) the probability that \( n(A \cap B)=2 \), is
\( \mathrm{P} \)
(A) \( \frac{{ }^{10} \mathrm{C}_{2}}{4^{10}} \)
(B) \( 5 .\left(\frac{3}{4}\right)^{10} \)
(C) \( \left(\frac{3}{4}\right)^{10} \)
(D) \( \frac{3^{8}}{4^{10}} \)
