Explanation



A parallelogram has two angles as seen in image below.




Now we know from the question = $\angle A - \angle B = 52$.

And $\angle A + \angle B + \angle A + \angle B =360$

Since sum of angles in a quadrilateral. is 360.

$2 \times (\angle A + \angle B) = 360$

or $\angle A + \angle B = 180$.

Solving for values of $\angle A$ and $\angle B$.

$\angle A = 116$ and $\angle B = 64$.

Hence C is correct
