C.
Step-by-step explanation:
A complementary angle is an angle at 90 degrees and is formed by 2 angles.
You can eliminate choice B because pulling two cards (from 52) does not accurately represent the deck since the sample size is too small.

There are 26 red cards (13 diamonds and 13 hearts) out of 52 total cards.
So the probability is 26/52 = 1/2, which means that the empirical probability can be determined. So choice C is out.

Another way is to pull out cards at random and make notes as to what color cards you are pulling. Then you can divide the count of red cards by the count of cards total. This is basically what choice A is describing.
So the answer is choice A</span>
