C Correct answer
Explanation

Total red cards = 26. Hearts = 13. Probability = 13 / 26 = 1/2.

AI explanation

Since the drawn card is known to be red, the reduced sample space consists of the 26 red cards. Out of these 26 red cards, 13 are hearts. Using the conditional probability formula, the probability that the card is a heart is 13 divided by 26, which simplifies to 1/2. Therefore, the probability is 1/2.
