radio buttons for a, b, c, d

Explanation:

To solve this, we analyze each option:

• Option A (Tropic of Cancer) is a latitude line, not longitude, so eliminate.
• Option B (Prime Meridian) is the 0° longitude line, a key longitude reference.
• Option C (Equator) is 0° latitude, not longitude, eliminate.
• Option D (International Date Line) is at 180° longitude but the Prime Meridian is more fundamental as the 0° reference for longitude. So the best answer is B.

Answer:

B. Prime Meridian
