Que. Consider the set {a, b, c} with binary operators + and × defined as follows :

+ a b c × a b c
a b a c a a b c
b a b c b b c a
c a c b c c c b

For example, a + c = c, c + a = a, c × b = c and b × c = a. Given the following set of equations :

(a × x) + (a × y) = c
(b × x) + (c × y) = c

The number of solution(s) (i.e., pair(s) (x, y)) that satisfy the equations is :
a. 0
b. 1
c. 2
d. 3
