Answer:
Option C
Explanation:
Given , 
A1 allele is carried by  % people
 % people 
Let us assume A1 s dominant genotype
This means 
Thus, frequency of allele in the given population is 
It is also given that the population is in Hardy-Weinberg equilibrium thus

Frequency of fruit fly with genotype A2A2 will be 

As per Hardy-Weinberg's second equation of equilibrium

Hence, option C is correct
