Simplify the Expression $$\sqrt [ 4 ] { 2 x y ^ { 5 } } + y \sqrt [ 4 ] { 512 x y } - \sqrt [ 4 ] { 2 x y ^ { 5 } }$$

Multiple Choice

Simplify the expression.Assume that all variables represent positive numbers, so that no absolute value symbols are needed. $$\sqrt [ 4 ] { 2 x y ^ { 5 } } + y \sqrt [ 4 ] { 512 x y } - \sqrt [ 4 ] { 2 x y ^ { 5 } }$$

A) $\quad 4 y \sqrt { 4 x y }$
B) $\quad 4 y \sqrt { 2 x y }$
C) $\quad 12 y \sqrt { 2 x y }$
D) $\quad 8 y \sqrt { 3 x y }$
