The correct answer is - temperate.
The temperate climates can simply be described as climates with milder temperatures. These climates have changes of seasons, four of them, spring, summer, autumn, and winter. The springs and autumns tend to have mild temperatures, the summers are warm, and the winters are cold, but the highest and lowest temperatures do not come close to the extremely high temperatures in the tropical zone, or extremely low temperatures in the high latitude zones. So these climates have temperatures that are in between the extremes of the low and high altitudes, thus they are milder climates.
