Question 1727Navigation General

The correct answer is D) 15°E. The standard time meridian for zone description -1 is 15°E. This is based on the International Date Line, which divides the world into 24 time zones, each 15 degrees of longitude wide. Zone description -1 refers to the time zone one hour behind UTC (Coordinated Universal Time), and the standard time meridian for this zone is 15 degrees east of the prime meridian at 0 degrees. The other options are incorrect because 0° is the prime meridian, 7 1/2°W is the standard time meridian for zone description -4, and 7 1/2°E is not a recognized standard time meridian.
