When the body needs to fight infectious diseases it increases the number of white blood cells.
a) diseases, it
b) diseases. It
c) diseases; it
d) No change is necessary.
D) No change is necessary.
The underlined portion "diseases it" is correct and doesn't require any changes. Therefore, the correct option is:
d) No change is necessary.
The underlined portion of the sentence is "diseases it," which indicates a problem with the use of punctuation. In this case, the correct punctuation to use would be a semicolon (;) because it is used to separate two closely related independent clauses.
So, the correct option to choose is c) diseases; it.
