Which graph represents positive acceleration ?

Which graph represents the uniform acceleration

STATEMENT - 1 : The slope on a position-time graph is representative of the acceleration of the object. STATEMENT - 2 : A straight, diagonal line on a position-time graph is representative of an onject with a constant velocity. STATEMENT - 3 : I an object is at rest, then the position-time graph must be a horizontal line located on the time-axis.

Graphs are very useful to represent a physical situation. Various quantities can be easily represented on graphs and other quantites can be determined from the graph. For example the slope of velocity-time graph represents instantaneous acceleration. For a motion with constant acceleration slope of velocity-time graph is constant. If acceleration is changing with time, slope with change and thus velocity-time graph will be a non-linear curve. Further the area of velocity-time graph gives displacement. The velocity-time graph for two objects P and Q are shown. The ratio of their respective acceleration is
