OFFICIAL EXPLANATION
Performing at least one hour of physical aerobic exercise a day is a must for children as it improves muscular fitness and bone health.
A. at least one hour of physical aerobic exercise a day is a must for children as it
This answer choice is grammatically incorrect. A pronoun (in this case, it) refers to a previously mentioned noun. If we wish to refer to a previously mentioned verb, we need to use the phrase to do so or doing so.
What helps us identify this question as a Pronoun question is the following Stop Sign: Any pronoun in the underlined part or after it.
B. at least one hour of physical aerobic exercise a day is a must for children as this

Although this answer choice corrects the grammatical Pronoun error in the original sentence by replacing the Pronoun it with the term doing so to refer back to the verb performing, it is stylistically flawed. The phrase one hour or more than one hour is redundant. Look for a more concise answer choice.
