Answer:
d. real Numbers
A general equation in two variables has infinitely many solutions if there is no restriction placed on the values of the two variables (x and y here). However, it may have a unique solution if certain constraints are placed on it. Here we can see by observation that if x and y are constrained to be natural numbers, then it has a solution f or x=y=1, and this is the only possible solution f or natural numbers.
