Solution

The correct option is D 8
The total number of gametes produced by a genotype can be calculated using the formula 2$$^n$$, where "n" is the total number of heterozygous genes present in the genotype. Since, the F$$_1$$ hybrids are heterozygous for three genes, the types of gametes produced in both male and female will be 2$$^3$$= 8. Hence, option D is the correct answer.
