Which option correctly identifies the graph that represents an object increasing its position with a constant velocity and describes why?

A --It is Graph D because a vertical line indicates the object is increasing its position, and a straight line means it is moving with a constant velocity.

B--It is Graph C because curving upward indicates the object is increasing its position, and a positive slope means it is moving with a constant velocity.

C--It is Graph A because a horizontal line indicates the object is moving with a constant velocity, and the positive value means it is increasing its position.

D--It is Graph B because a straight, diagonal line indicates the object is moving with a constant velocity, and a positive slope means it is increasing its position.
