Answer: 1/4 (choice C)

Step-by-step explanation:

Assuming this deck only has 13 clubs and 13 hearts, then we have 13+13 = 26 cards total. Of those 26, we have 13 clubs. So 13/26 = 1/2 of the cards are clubs.

(1/2)*(1/2) = 1/4 is the probability of getting 2 clubs in a row when replacement is done.
