Stepwise Solution:
Step 1: Understand the doctrine.
The "Tender Years Doctrine" is a legal principle in family law. It is based on the belief that during a child’s formative years (generally under 13), the mother is presumed to be the more suitable custodian.
Step 2: Eliminate irrelevant options.
- Option 1: Minimum legal age to marry → Not related to custody.
- Option 3: Statutory rape → Relates to criminal law, not family law.
- Option 4: None of the above → Incorrect because Option 2 is correct.
Step 3: Match with correct context.
The doctrine specifically addresses custody of children in divorce or separation proceedings.
✅ Correct Answer: Option 2 — Custody of child in divorce proceedings.
Explanation: Under this doctrine, courts historically favored mothers for custody of young children, assuming they are better suited to provide care. Though modern laws focus more on "best interest of the child," the tender years doctrine was a key traditional principle.
