B Correct answer
Explanation

Each coin toss is an independent event. The previous outcomes do not affect the probability of the sixth toss.

AI explanation

Because a coin has no memory, each individual toss is an independent event. The outcome of the first five tosses, whether heads or tails, has absolutely no effect on the outcome of the sixth toss. Since the coin is unbiased, the probability of getting a tail on the sixth toss remains 1/2.
