The answer is C) 3/4

Let's analyze separately each of the traits:

Parental generation: AA x Aa
F1 generation:       AA AA Aa Aa
So, all progeny will <span>phenotypically resemble the first parent.

</span>Parental generation: BB x bb
F1 generation:       Bb Bb Bb Bb
So, all progeny will <span>phenotypically resemble the first parent.
</span>
Parental generation: Cc x Cc
<span>F1 generation:       CC Cc Cc cc
</span>Only 3 (CC, Cc, Cc) out of 4 progeny will <span>phenotypically resemble the first parent.

The genotypes for first two traits will not affect </span>phenotypical resemblance to the first parent. So, it only counts the third trait, for which the chance to have progeny that <span>phenotypically resemble the first parent is 3/4.</span>
