Option 1 : Only B
Concept:
Motion:
- A body is said to be in motion if its position changes continuously with respect to the surroundings with time.
- The motion of an object could be uniform or non-uniform depending on whether its velocity is constant or changing.
- Uniform and non-uniform motions of objects can be shown through graphs.
- The speed of an object is the distance covered per unit of time.
Uniform Motion:
- It is a motion in which a material point moves in a straight line and covers equal distance in equal intervals of time.

Non-uniform Motion:
- It is a motion in which the velocity varies with time.

Explanation:
- The change in the position of an object with time can be represented on the distance-time graph.
- When an object travels equal distances in equal intervals of time, then it moves with uniform speed.
- This shows that the distance traveled by the object is directly proportional to the time taken.
- Thus, for uniform speed, a graph of distance traveled against time is a straight line.
Therefore, from the above discussion, the correct answer is B) It is moving with uniform speed.
