Maybe a Line graph. C.

Answer 2

Answer:

Option C, line graph

Explanation:

A line graph is the best graphical tool to represent  any quantity that changes continuously with time.

Here,  when certain dosage of a certain medicine (which is to be tested) is given to a patient then the impacts produced by the medicine on the patient will be changing continuously. Thus, in order to capture  these continuous changing values, it would be best to use a line graph.

Hence, option C is correct.
