D. ADD a semicolon, then the transition, then the comma between two independent clauses

Explanation:

A "run on" sentence is the one in which two independent clauses are incorrectly joined. We can correct them by either punctuating them properly and separating them or by making it a complex sentence.

In the given run on sentence, semicolon can be added and then comma can be used between the transition (however) and the other independent clause. Semicolon is usually added to denote that the two independent sentences refer to the same thing. This way we can make the sentence proper. We can it as "the student completed the exam; however, they failed because they did not study." We have used semicolon after the first independent clause and then we inserted the transition (however) followed by a comma and then the next independent clause.

D. ADD a semicolon, then the transition, then the comma between two independent clauses

Explanation:

Run on sentences refer to two sentences merged without incorrect punctuation or linking words. Since both clauses are complete and independent sentences which make sense on their own, they can be combined into one compound sentence. Thus, they can be joined with a semicolon and the transitional word however, to indicate contrast, followed by a comma:

The student completed the exam; however, they failed because they did not study.
