The phrase 'the main responsibility for children' refers to:

• A. The person who arranges childcare services.
• B. The person who handles the majority of direct childcare tasks.
• C. The person who finances childcare.
• D. The person who makes school choices.

Answer: (B)

The main responsibility for children refers to who does the day-to-day, hands-on care. It’s about the direct tasks involved in looking after children—feeding, supervising, comforting, helping with homework, and staying with them when they’re ill. Those ongoing, direct care duties are what this phrase points to as the primary burden or role.

So the best answer is the person who handles the majority of direct childcare tasks because that captures who is actually performing the routine care that keeps children cared for on a daily basis. The other options describe more organizational or financial roles (arranging external care, funding care, making schooling choices) but don’t reflect who is doing most of the actual caregiving.
