Answer:

Option A

Explanation:

First let's make see the what is the difference (they are not the same thing.) And then lets analize which statement is the most accurate.

A change in supply and a change in quantity supplied are different things.   The change in supply is caused by changes in costs and incentives that change how much a producer can and will produce at a given price.

The change in quantiy supplied is caused simply by a change in the retail price of the product.
