Step 1: Understand the question.
We must find which section of the Code of Criminal Procedure, 1973 gives a quick remedy for maintenance to spouses, children, and parents who cannot support themselves.
Step 2: Know the purpose of the provision.
This is a social welfare rule. Its aim is not to punish but to stop people from becoming destitute when a person who has the means neglects to support his family members.
Step 3: See who can claim.
A wife who cannot maintain herself, a minor child, a grown-up child with a serious disability, and parents who cannot support themselves can all claim. If the person who must support them has means but refuses, the Magistrate can order payment.
Step 4: Recall the correct section.
Section 125 of the CrPC is the famous maintenance provision. It works for people of all religions and gives a fast, cheap, summary remedy.
Step 5: Check the other options.
Section 320 is about compounding of offences. Section 144 deals with urgent nuisance or danger. Section 107 deals with security for keeping the peace. None of these is about maintenance.
Step 6: Reach the answer.
Since only Section 125 gives a summary maintenance remedy to wives, children, and parents, that is the correct option.
\[ \boxed{\text{Section 125}} \]
