C)abnormal.Elbert needs further evaluation for lung problems
IS B CORRECT ANSWER?THANK YOU:)))

I disagree. No doctor recommends illness to build up immunities. Doesn't 8 colds seem excessive to you?

Each fall, the choir teacher faces the task of retraining the deepening voices of some of his male students. What period of development are these students most likely in?

Yes, option B is the correct answer. Catching eight colds in one year is considered normal and can actually be beneficial for a young child like Elbert. This is because colds help the immune system develop by building up natural immunities. Through exposure to different viruses, the immune system learns to recognize and fight off those viruses more effectively in the future.

Colds are common in children, especially those who attend school or daycare, as they come into contact with many other children who may be sick. It is not uncommon for young children to catch multiple colds in a year as their immune systems are still developing. Therefore, Elbert does not need further evaluation for lung problems as mentioned in option C. Additionally, option D is not correct because catching multiple colds helps the body develop immunities, not the opposite.
So, the correct answer is B) normal. They helped Elbert build up natural immunities.
