The LCM and HCF of two monomials is \( 60 x^{4} y^{5} a^{6} b^{6} \) and \( 5 x^{2} y^{3} \) respectivel \( y \). If one of the two monomials is \( 15 x^{4} y^{3} a^{6} \), then the other monomial is
(a) \( 12 x^{2} y^{3} a^{6} b^{6} \)
(b) \( 20 x^{4} y^{5} b^{6} \)
(c) \( 20 x^{2} y^{5} b^{6} \)
(d) \( 15 x^{2} y^{5} b^{6} \)
