✅ Solution Explanation
(B) its effect on productivity is minimal, and it can even sometimes be counterproductive when consumed in excess ✅
- Rule 1: Parallel structure — the subject (“its effect”) must align with verbs in both clauses.
- Rule 2: “and it can” is required — you cannot omit “it” in the second clause.
(B) its effect on productivity is minimal, and it can even sometimes be counterproductive when consumed in excess ✅
