Options

A. increasing
B. decreasing
C. constant
D. zero

Explanation

To solve the question, "If an object is moving with a constant acceleration, the net force acting on that body is?", we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Concept of Acceleration**:
- Acceleration (A) is defined as the rate of change of velocity of an object. If the acceleration is constant, it means that the velocity of the object is changing at a steady rate.

**Hint**: Recall the definition of acceleration and its relation to velocity.

2. **Identify the Mass of the Object**:
- The mass (M) of an object is a measure of the amount of matter in it and does not change regardless of the object's state of motion (whether it is at rest or in motion).

**Hint**: Remember that mass is a scalar quantity and remains constant unless the object loses or gains mass.

3. **Apply Newton's Second Law of Motion**:
- According to Newton's second law, the net force (F) acting on an object is given by the equation:
\[ F = M \times A \]
- Here, F is the net force, M is the mass, and A is the acceleration.

**Hint**: This law states that the force acting on an object is equal to the mass of the object multiplied by its acceleration.

4. **Determine the Nature of Mass and Acceleration**:
- Since both mass (M) and acceleration (A) are constant (as stated in the question), we can conclude that the product of these two constants (F) will also be constant.

**Hint**: Think about how multiplying two constants affects the result.

5. **Conclude the Result**:
- Therefore, if both mass and acceleration are constant, the net force acting on the body must also be constant.

**Hint**: Summarize the relationship between constant mass, constant acceleration, and constant force.

### Final Answer:
The net force acting on the body is constant.
