All three statements regarding longitudes and latitudes are correct.

Longitudes are imaginary lines running from the North Pole to the South Pole. They are furthest apart at the equator and converge at the poles, where the distance between them becomes zero. The equator is the largest circle of latitude, and the distance between longitudes is maximum here. There are 360 degrees of longitude (180° East and 180° West from the Prime Meridian, including 0° and 180°). Latitudes are imaginary circles parallel to the equator. There are 181 lines of latitude (0° at the equator, 1° to 90° North, and 1° to 90° South). Thus, the number of longitudes (360) is greater than the number of latitudes (181).

Lines of latitude are parallel and the distance between consecutive degrees of latitude is approximately constant (about 111 km or 69 miles). Lines of longitude are not parallel; their distance varies from maximum at the equator to zero at the poles.
