Which of the following statements can be possible cases in one//two dimensional motion ?

Options

A. A body has zero velocity and is still accelerating.
B. The velocity of an object reverses direction when acceleration is constant.
C. An object's speed goes on increasing even magnitudes of its acceleration decreases.
D. None of these

Explanation

To solve the question regarding which statements can be possible cases in one-dimensional or two-dimensional motion, we will analyze each statement one by one.

### Step-by-Step Solution:

**Step 1: Analyze the First Statement**
- **Statement:** A body has zero velocity and is still accelerating.
- **Explanation:** This can occur in vertical motion, such as when an object is thrown upwards. At the peak of its motion, the velocity is zero, but the acceleration due to gravity is still acting on it (approximately 9.8 m/s² downwards). Thus, this statement is **correct**.
