Step 1: Understand the question.
We need the section of the Code of Criminal Procedure (CrPC), 1973, that gives a quick remedy for maintenance, meaning money support, to spouses, children, and parents who cannot support themselves.
Step 2: Recall the purpose of maintenance law.
This is a social welfare rule. Its aim is to stop people who are left without support from falling into poverty or being forced to beg.
Step 3: Match it to the right section.
Section 125 of the CrPC is exactly this provision. It lets a Magistrate order a person to pay maintenance to his wife, children, or parents who cannot maintain themselves. It works fast and is open to everyone, whatever their religion.
Step 4: Check the other sections.
Section 320 deals with compounding (settling) of offences. Section 107 deals with keeping the peace. Section 144 deals with urgent orders to prevent nuisance or danger. None of these is about maintenance.
Step 5: Confirm the match.
Only Section 125 fits the description of a summary remedy for maintenance of dependents.
Step 6: State the answer.
The correct provision is Section 125.
\[ \boxed{\text{Section 125}} \]
