When a body rolls without sliding up an inclined plane the frictional force is :

Options

A. directed up the plane
B. directed down the plane
C. zero
D. dependent on its velocity

Explanation

To solve the problem of determining the direction of the frictional force when a body rolls without sliding up an inclined plane, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Forces Acting on the Body:**
- When a body rolls up an inclined plane, the gravitational force acting on it can be resolved into two components: one parallel to the incline (`mg sin θ`) and one perpendicular to the incline (`mg cos θ`).

2. **Analyze the Motion:**
