As discussed in Hardy Weinberg Equilibrium -

 

 

According to Hardy - Weinberg equilibrium, 
(p + q) 2 = 1 or  p2 + q2 + 2pq = 1 
As per this question, 
p2 (AA) = 360 and  q2 (aa) = 160 
Frequency of the allele ‘A’ would be 360/1000 = 0.36
Therefore p would be √0.36  = 0.6 
Hence, the correct option is (c).
