The correct option is C AABbCCddEE
Formula to calculate how many different types of gametes can be formed is 2n, where n is the number of heterozygous genes/ allele pairs.
The AABbCCddEE genotype has one heterozygous gene pair of Bb, hence it will form 2 types of gametes, ABCdE and AbCdE.
AABbCCddEE produces only 2 types of gametes as shown below:
AABbCCddEE
↓
ABCdE & AbCdE
AaBbccDd forms 23 = 8 kinds of gametes.
AaBbccDDEe forms 23 = 8 kinds of gametes.
AaBbCcDDEe forms 24 = 16 kinds of gametes.
