Hey guys..please help me in this problem ???

Suppose that MUx/Px exceeds MUy/Py (MU = marginal utility and p= price). To maximize utility the consumer who is spending all her money income should buy:
a) less of X only if its price rises.
b) more of Y only if its price rises.
c) more of Y and less of X.
d) more of X and less of Y.

according to me answer should be "d".. would that be right as its not mentioned in question that prices are fixed or perfect competition exists!!
