Answer: D

Explanation:

An exponential moving average (EMA) is a type of moving average (MA) that places a greater weight

and significance on the most recent data points. The exponential moving average is also referred to

as the exponentially weighted moving average. An exponentially weighted moving average reacts

more significantly to recent price changes than a simple moving average (SMA), which applies an

equal weight to all observations in the period.
