B) gain 40 pounds by the end of summer

C)lode 20 pounds by the end of the year

D) gain 20 pounds by the end of the month

A

Explanation:

First we have to know what BMI is and when we see the definition  means "Body Mass Index (BMI) is a person's weight in kilograms divided by the square of height in meters."

Now that we know that, We are now going to find the answer so when we look at the bmi chart down below it says that the weight of 5'4 would be 162.5 Lbs. Knowing that, We know that he wants to "achieve a normal body composition within six months" So we also know that D is wrong because that is not healthy and rememeber he wants to have a healthy weight he doesnt want to gain 20 pounds by the end of the month because he says he wants to maintain a normal body composition within six months. C is unhealthy because remeber he wants to stay healthy he doesnt want to be to be underweight he is trying to gain weight, And B is wrong because it is unhealthy and you don't want to gain 40 pound in 4 months because gaining that much weight can cause health problems including different cancers and maybe even diabetes. So we know that the answer is A because he wants to maintain a constant weight a healthy weight. So he Gained 5 pounds by the end of February.
