If the speed were constant, then the distance would increase by a constant amount per unit of time. This would give a straight line (with a slope corresponding to the speed).
If the speed increases steadily, then for each unit of time, the new distance (added to the old distance) would be a bit more. The graph would show a line that climbed faster and faster with time: a curved line, with the slope increasing steadily. The slope still shows the speed (increasing steadily). The rate of increase of the slope (meaning: the slope of the slope) is called the acceleration.
If you want to get technical about it: the graph would be a portion of a parabola.
If the graph could be represented by a function of time f(t), then f(t) would be the distance traveled at time t.
The first differential (the slope fo f(t)), often written f'(t), is the speed.
The second differential f"(t) is the acceleration.
It really becomes easy once you've done a few.

Not sure what you mean. If this is a graph measuring distance vs. time, their would not be a specific line to represent speed.
However, the graph of distance vs. time with a steadily increasing speed would be represented by a curved line with a virtually flat slope at the start and an increasing slope as x (time) increases. As the speed increases, the distance traveled during each second becomes greater than the second before it, causing the increasing slope.
If you have a steadily increasing speed and you were to creat a draft measuring spped vs. time, that would be a straight line with a constant slope.

On a distance time graph, speed is the gradient of the line. Since the speed is steadily increasing, the answer is d.

If acceleration is constant a graph of distance vs time will be a parabolic curve.

curved line going upward to the right if the speed is steadily increasing.
