For this case we must rationalize the following expression:


\frac {2 \sqrt {5}} {- 3 \sqrt {50}}

Multiply the numerator
\sqrt {50}:


\frac {2 \sqrt {5} * \sqrt {50}} {- 3 \sqrt {50} * \sqrt {50}} =\\\frac {2 \sqrt {5 * 50}} {- 3 (\sqrt {50}) ^ 2} =\\\frac {2 \sqrt {250}} {- 3 * 50} =\\\frac {2 \sqrt {250}} {- 150}

Answer:

Option B
