Which of the following represents an affirmative voice vote?

An affirmative voice vote is signaled by the term "Aye," which indicates support or agreement with the motion or proposal being considered. When members of a group cast their votes verbally, saying "Aye" shows that they are in favor of what is being discussed. This is a standard practice in parliamentary procedure, where the votes are typically called out in response to the chair's request for those in favor.

The other options do not represent an affirmative vote. "Nay" indicates opposition, meaning that those who say it are voting against the motion. "Present" signifies that someone is in attendance but does not indicate support or opposition. Similarly, "Abstain" means that a member chooses not to vote either in favor or against the motion, thus remaining neutral. Each of these terms serves a specific role in the voting process but does not convey support like "Aye." Therefore, "Aye" is the correct term to represent an affirmative voice vote in this context.
