Correct option (b) Four

Explanation

First pair AA is homozygous hence, it will contribute only one type of gene to gametes, Bb will yield two types of gametes --- B and b similarly, Cc will yield two types of gametes-C and c. Hence, 1 x 2 x 2 =4 types of gametes would be produced having the genotypes ABC, ABc, AbC and Abc.
