See the picture attached to better understand the problem
we know that
the <span>smallest face of the prism is the face ABCD
</span>so
the <span>shape of the two-dimensional cross-section is a rectangle 9 in x 10 in
therefore
the answer is
the option </span><span>C.
a 9-inch by 10-inch rectangle</span>
