B
4(2x + y)
C
4(2x + 2y)
D
8(x + y)
Explanation: 

Detailed explanation-1: -Combine any like terms on each side of the equation: x-terms with x-terms and constants with constants. Arrange the terms in the same order, usually x-term before constants. If all of the terms in the two expressions are identical, then the two expressions are equivalent.

Detailed explanation-2: -Examples of Equivalent Expressions 3(x + 2) and 3x + 6 are equivalent expressions because the value of both the expressions remains the same for any value of x. 3x + 6 = 3 × 4 + 6 = 18. and can also be written as 6(x2 + 2y + 1) = 6x2 + 12y + 6.

Detailed explanation-3: -Therefore, the equivalent expression is (4y^2)^9.
