For motion in a straight linea)motion away from origin is positiveb)mo...
Explanation:To describe motion along a straight line, we can choose an axis, say X-axis, so that it coincides with the path of the object. We then measure the position of the object with reference to a conveniently chosen origin, say O, Positions to the right of O are taken as positive and to the left of O, as negative.

Explanation:
When we talk about motion in a straight line, we need to establish a reference point or origin to measure the position of the object. The position of the object can be either to the left or right of the origin. The direction of motion can also be towards or away from the origin.
Direction of Positive Motion:
In order to establish a convention for measuring the position and direction of motion, we need to choose a direction as positive. This is usually done based on the context of the problem. For example, if we are talking about a car moving on a highway, we might choose the direction of motion of the car as positive. Similarly, if we are talking about a projectile moving upward, we might choose the upward direction as positive.
Direction of Positive Position:
Once we have chosen the direction of positive motion, we need to choose a direction as positive for measuring the position of the object. This is usually done based on convention. In most cases, the convention is to take the direction of motion as positive. However, in some cases, it may be more convenient to take the opposite direction as positive.
Convention for Position in Straight Line Motion:
In the case of motion in a straight line, the convention is to take the right direction as positive and the left direction as negative. This convention is commonly used in physics and mathematics. So, if an object is to the right of the origin, its position is positive and if it is to the left of the origin, its position is negative.
Conclusion:
Hence, option D is the correct answer as it states that the convention for motion in a straight line is to take the position to the right of the origin as positive and to the left of the origin as negative.

In most cases, the convention is to take the direction of motion as positive. However, in some cases, it may be more convenient to take the opposite direction as positive.
Convention for Position in Straight Line Motion:
In the case of motion in a straight line, the convention is to take the right direction as positive and the left direction as negative. This convention is commonly used in physics and mathematics. So, if an object is to the right of the origin, its position is positive and if it is to the left of the origin, its position is negative.
Conclusion:
Hence, option D is the correct answer as it states that the convention for motion in a straight line is to take the position to the right of the origin as positive and to the left of the origin as negative.
