Explanation:

In a dihybrid cross, during F2 generation 16 progeny are formed, in this, 10 progeny shows parental phenotypes, remaining 6 progeny shows new phenotypes. These are called recombinants. So, in the F2 generation 1280 progeny are formed, in this 800 progeny shows parental phenotypes and 540progenies are recombinants.

So, the correct option is ‘540
