Answer:

8n

Explanation:

Female = '6n' no. of chromosomes

Male = '4n' no. of chromosomes

Female gamete or ploidy of egg = 3n

Male gamete or ploidy of sperm = 2n

During zygote formation, male and female gametes fusion takes place,

2n + 3n = 5n

For endosperm formation,

2 polar nuclei + 1 male gamete = 6n + 2n = 8n.

So, the correct option is '8n'.
