Question 1488Navigation General

The correct answer is C) Horizontal libration. The four types of lunar libration are: diurnal libration, physical libration, libration in longitude, and libration in latitude. Horizontal libration is not one of the types of lunar libration. Diurnal libration, physical libration, and libration in latitude are the correct options among the choices provided. The other options are incorrect because diurnal libration is the daily oscillation of the Moon's visible surface, physical libration is the actual physical wobbling of the Moon, and libration in latitude is the north-south oscillation of the Moon's surface.
