Answer:

A.Change Step

Explanation:

The closed change is a Pre-Bronze, or newcomer waltz figure, performed in closed position.[1] Changes may start of the right foot or left foot, moving forward or backward. This makes four different types of closed changes. Combining two changes results in a box step. In right changes the man starts from the right foot, while in left ones the man starts from the left foot.

The figures are called "changes" because they allow dancers to change from natural turn to reverse turn (i.e., left to right turn) and vice versa. For example, a basic practising variation in waltz goes as follows:

Dance 1–6 steps of natural turn,

then 1–3 steps of closed change from natural to reverse,

then 1–6 steps of reverse turn,

then 1–3 steps of closed change from reverse to natural,

repeat until the music stops or partner drops.
