The answer shown above is the only answer choice that mentions an angle.

__

<em>Comment on other choices</em>

Choice B shows the three sides are proportional, so would be useful if the SSS similarity theorem were to be invoked. It isn't helpful for the using the SAS similarity theorem.

Choices C and D get the proportion statements wrong.
