Answer 1

For this case, the first thing we will do is define the following functions:
 Function orange = D (x)
 Blue function = D1 (x)
 Let's see how one function varies with respect to the other:
 D1 (x) = D (x) - 2.5
 Therefore, we see that the function decreases.
 Answer:
 B. A decrease in demand

Answer 2

The answer to your question is that it describes the decrease in demand. So option letter B is correct. Letter D is incorrect because it is obvious in the title of thw graph which is only a quantity demanded.
