Answer
(a) Oxidising power of X > Y. Elements with high electron affinity accept electrons more easily hence have greater oxidising power.
(b) Electronegativity of X > Y. Element with high electron affinity has high electronegativity.
(c) X is to the right side of Y as electron affinity increases from left to right in a period.
