Answer:
The sentence that is complete and properly punctuated is sentence D.
Step-by-step explanation:
The sentence above illustrates the correct use of the semicolon. You should use a semicolon between two independent clauses linked by a transitional expression. An independent clause is a sentence that represents a complete thought and therefore can stand alone as a sentence (see 1 and 2).
In D, the transitional expression is "as a result". Then, a comma follows this phrase as it functions as the introduction to the rest of the second clause (2).
