C Correct answer
Explanation

Option C matches the given expression (x+y)^2=x^2+xy2+y^2. The notation xy2 appears to represent the middle term 2xy in the binomial expansion. The standard form of (x+y)^2 is x^2 + 2xy + y^2, but this question uses compressed notation where xy2 serves as the middle term.
