The doctor tells him that some extra protein is fine but warns him about consuming too much. The statement which best explains the doctor's advice is too much protein can cause issues with the kidneys and is denoted as option C.
This is referred to as a biological molecule which contains amino acids and is responsible for the growth and repair of worn out tissues in organisms. Sources of protein include beans, meat etc and should be taken moderately.
Too much protein can lead to an increase in the pressure of kidneys in filtering out waste from the body which is referred to as hyperfiltration. In the long run, this could lead to kidney damage as a result of the persistent stress.
