Explanation:

A run - on sentence (fused sentence or comma splice) occurs when two independent clauses are joined without proper punctuation or a conjunction. Let's analyze each option:

• Option 1: Uses a semicolon to separate two independent clauses, which is correct punctuation.
• Option 2: "Some people who work at home miss socializing with their colleagues" and "isolation and depression are two of the most common hazards of working at home" are two independent clauses joined without proper punctuation (just "in fact" which is not a conjunction or proper punctuation here), so this is a fused sentence (run - on).
• Option 3: Uses a semicolon to separate the independent clauses, which is correct.
• Option 4: Uses a period to separate the independent clauses, which is correct.

Answer:

B. Some people who work at home miss socializing with their colleagues in fact isolation and depression are two of the most common hazards of working at home.
