The time to file an answer after service is which of the following?

• A. 60 days
• B. 30 days
• C. 20 days
• D. 10 days

Answer: (C)

The main idea is the deadline for a defendant to respond to a lawsuit after being served. When someone is served with a summons and complaint, they must file an answer within a limited period to start defending the case and to keep it moving toward resolution. In many civil-procedure contexts used in this material, the standard period is twenty days. This short window ensures the process proceeds promptly and helps prevent delays or default judgments.

There are situations where the deadline can be longer, such as when service is by mail or when a waiver of service is used, but absent those exceptions, twenty days is the default rule. The other timeframes listed are not the typical default period in this context, which is why twenty days is the best answer.
