C Correct answer
Explanation

Each coin toss is an independent event with a probability of 1/2 for heads. The outcome of the fourth toss is independent of the other tosses.

AI explanation

Because each toss of a fair coin is an independent event, the outcome of the fourth toss does not depend on the outcomes of the previous three tosses. The sample space for a single coin toss consists of two equally likely outcomes, which are heads and tails. The probability of getting a head on the fourth toss is therefore 1 out of 2, which equals 1/2.
