A) $\frac { \partial z } { \partial x } = \frac { 13 y ^ { 2 } } { \sqrt { x } }$
B) $\frac { \partial z } { \partial x } = \frac { 26 } { \sqrt { x } }$
C) $\frac { \partial z } { \partial x } = 13 y ^ { 2 } \sqrt { x }$
D) $\frac { \partial z } { \partial x } = \frac { 13 } { x }$
E) $\frac { \partial z } { \partial x } = 13 y ^ { 2 }$
