Verification of truth — personal-law nuance (India context): “A lady in India can marry the brother of her deceased husband, but no man can marry the sister of his deceased wife.” — Choose the most accurate frequency statement.

Introduction / Context:
This “verification of truth” item asks whether a two-part social/legal claim holds universally in India. Personal laws in India vary across religions and communities, and customs can carve out exceptions. Hence, such statements are rarely “Always/Never” true. We must judge the most accurate frequency descriptor.

Given Data / Assumptions:

• India recognizes multiple personal-law systems (Hindu, Muslim, Christian, Parsi, civil law under the Special Marriage Act) and community customs.
• Relationships within prohibited degrees can sometimes be permitted by established custom.
• The claim has two parts: (1) widow marrying her deceased husband’s brother; (2) widower marrying his deceased wife’s sister.

Concept / Approach:
We must check whether each part is universally true. In many personal-law frameworks, both unions may fall within prohibited relationships unless permitted by custom or specific legal provisions. Therefore, neither part is universally allowed or universally barred across all communities and contexts.

Step-by-Step Solution:
Analyze part (1): In several communities, a widow marrying the deceased husband’s brother (levirate-like union) may be permitted by custom; in others it is prohibited.Analyze part (2): A widower marrying his deceased wife’s sister is permitted under some frameworks and customs, but prohibited in others as a degree of affinity.Since outcomes depend on law/custom, a mid-scale frequency word fits best.

Verification / Alternative check:
Because both permissions/prohibitions exist depending on religion, statute, and custom, neither “Always” nor “Never” applies. “Generally” still overstates uniformity. “Sometimes” captures legal/customary variability.

Why Other Options Are Wrong:
Always/Never: contradicted by documented exceptions; Generally: still too strong across diverse personal laws.

Common Pitfalls:
Assuming one community’s rule applies to all; ignoring custom-based permissions.

Final Answer:
Sometimes
