Answer:
A. When two clauses are joined by a semicolon, they can usually be separated into two sentences.
Step-by-step explanation:
A semicolon (;) is used to join two independent sentences into one written sentence. This semicolon is used when the two sentences are seen to be closely related to be separated by the use of a full stop. Also, it is used when there is no connecting word that require the use of comma.
But in actual sense, a semicolon can be replaced by a full stop thereby forming two different sentences.
The two clauses joined by a semicolon can be separated into two sentences.
