Context: People can use the engineering-design process to develop solutions to problems. One step in the process is testing if a potential solution meets the requirements of the design.
The passage below describes how the engineering-design process was used to test a solution to a problem. Read the passage. Then answer the question below.

Michael, a materials engineer, was developing a quick-drying fabric for athletic clothing. The fabric needed to absorb one drop of water in less than one second and dry completely in less than five minutes. Michael thought a fabric made from cotton and polyester would both absorb water well and dry quickly. But he needed to decide what percentage of each material to use.
So, he made a sample fabric that was 50% cotton and 50% polyester. Then he put one drop of water on the sample. He timed how long it took the fabric to dry after the water was absorbed.
Figure: fabric that has not absorbed drops of water.
Which of the following could Michael's test show?
A. if the sample fabric would absorb one drop of water in less than one second
B. how long it would take the sample fabric to dry after it absorbed one drop of water
C. how much athletes would sweat in the fabric
Determine the correct option from the provided choices and reply with its corresponding letter.
