All Options:

  • AMoving average

  • DNone of these

Detailed Solution & Explanation

**Step 1: Understand the definition.** A **Moving Average** is computed by taking averages of successive overlapping groups of a fixed number of items from a time series. Each average overlaps with the previous one by sharing some common items. **Step 2: Elimination of wrong options.** - Weighted average assigns different weights to different items — not relevant here. - Simple average is the ordinary mean of all items — not overlapping groups. - None of these is incorrect since the answer is Moving Average. **Step 3: Conclusion.** The correct term is **Moving Average**. Hence, **Option A** is the correct answer.
