Answer should be B.
Product that is both a perfect cube and a perfect power of five would imply powers of 15. Simply, addding exponent of x,y & z with the given (x^3*y^2*z) in option B would yield x^(3+12)*y^(2+13)*z^(1+14) which equals x^15*y^15*z^15 = (xyz)*15 which is both a perfect cube as well as perfect power of five.
