If x and y are positive integers, is the total number of positive divisors of $$x^5$$ a multiple of total number of positive divisors of $$y^9$$

a) x=6
b) y=1

Kudos to correct answer and explanation. Caveat- this is a hard problem from Manhattan discussion forums( their 700 level problems on portal)
