Question

Read the passage underlined (2). There may be a mistake in punctuation, capitalization, or spelling. If you find a mistake, choose the answer that corrects the mistake. If there is no mistake, choose ‘Correct as is.’ A) Correct as is. B) while the President is on board the term is commonly used C) while, the President is on board, the term is commonly used D) while the President, is on board, the term is commonly used

Answer 1

The answer to your question would be that the selected sentence is correct as is. That is, the correct option would be A.

D separates the subject from the predicate and the commas in C are not necessary. All the sentences do not have the first letter of the first word capitalized. Therefore, none of them corrects the mistake.

Answer 2

I know that answer choice c and d are incorrect.

"C) while, the President is on board, the term is commonly used >> no comma is need here.
D) while the President, is on board, the term is commonly used" >> still, no comma is needed.

B) while the President is on board the term is commonly used

So A is the answer.
Should read >> While the President is on board, the term is commonly used.

Hope this helps.
