B. Only longitude lines that are labeled East pass through the equator.
C. Only longitude lines that are labeled West pass through the equator.
D. All lines of longitude pass through the equator.

Answer 1

All lines of longitude pass through the equator, regardless of whether they are labeled East or West.

Step-by-step explanation:

In answering the question of whether any of the lines of longitude pass through the equator, the correct answer is D. All lines of longitude pass through the equator. The lines of longitude, also known as meridians, run from the North Pole to the South Pole and cross the equator at right angles. The prime meridian, which is designated as 0° longitude, is the starting point for measuring longitude and it passes through the Royal Observatory in Greenwich, England. All other meridians are measured east or west of this line up to 180°. Therefore, it doesn't matter if they are labeled East or West; all longitudes intersect with the equator.
