Choice: [A]: "comma" — is INCORRECT. Note that placing a "comma" would result in an error known as "comma splice".

Choice: [C]: "period" — is INCORRECT. Note that placing a "period" would be incorrect. Doing so would result in a new sentence that does not begin with a capital letter.

Choice: [D]: "no punctuation is needed" —is INCORRECT. Note that if the statement were left alone, the statement would be a "run-on sentence".

The correct answer is: [B]: "semicolon". If a new sentence could be formed; and if the ideas could connect; it is acceptable to place a "semicolon" between the "two potential statements to form one statement" ; and to NOT CAPITALIZE the first word of the "second [potential sentence]" —unless that "[second potential sentence] begins with a proper pronoun.
