A member of an assembly has the right to do which of the following?

Participating fully in the proceedings of an assembly is a fundamental right of a member. This includes the ability to engage in discussions, propose motions, ask questions, and vote on issues that are being considered. Full participation ensures that all members have a voice in the decision-making process and that their opinions and ideas can be heard and considered by the assembly.

Option to make decisions without a vote undermines the democratic process inherent in most assemblies, where decisions should be made collectively. Direct communication with legislative bodies typically involves procedural protocols and may not be an individual member's right. Lastly, voting is generally open to all members and not restricted to when the chair calls on them, allowing members to express their opinions and participate in the decision-making process actively. Hence, option B stands as the most accurate representation of a member's rights within an assembly.
