Final answer:
The limitation on proxy is that it is only valid for the specific meeting it is issued for.
Step-by-step explanation:
The correct answer is C. The proxy as a rule is only for the meeting from which it is issued. A proxy is a document that gives someone else the authority to vote on behalf of a shareholder at a company's annual meeting or other important corporate events. The proxy agreement is typically only valid for the specific meeting it is issued for and does not extend beyond that.
