Section 125(4) bars maintenance in three situations: living in adultery, refusing without sufficient reason to cohabit, or mutual separation. Voluntary refusal to live with husband (option B) without justification directly triggers this bar.

1. 1 Pick up CrPC.
2. 2 Go to Section 125(4).
3. 3 Read: wife NOT entitled if (a) living in adultery, (b) refuses to live with husband without sufficient reason, (c) living separately by mutual consent.
4. 4 Option B (voluntarily refuses) matches ground (b). Note: 'husband presumes' is not the same as 'wife is actually in adultery.' Option B is the clearest match.

The text reads: Section 125(4): No wife shall be entitled to maintenance if she lives in adultery, refuses without sufficient reason to live with husband, or lives separately by mutual consent.
