Rationalize the Denominator and Simplify $\frac { 2 } { 7 - \sqrt { 10 } }$

Rationalize the denominator and simplify. Assume that all variables represent positive real numbers.
- $\frac { 2 } { 7 - \sqrt { 10 } }$

A) $\frac { 2 } { 7 } - \frac { 2 } { \sqrt { 10 } }$
B) $\frac { 14 - 2 \sqrt { 10 } } { 39 }$
C) $\frac { 14 + 2 \sqrt { 10 } } { 39 }$
D) $\frac { 14 + 2 \sqrt { 10 } } { 3 }$
