Đáp án: B

Giải thích:

Câu này hỏi về cách rút gọn mệnh đề trạng ngữ “when +S +V….”. Khi hai vế có chung chủ ngữ, ta có thể rút gọn chủ ngữ ở vế trạng ngữ, và hình thức động từ sẽ biến đổi.

Với dạng chủ động: When + V- ing.

Với dạng bị động: When + VpII

Vì chủ ngữ “alcohol” (chất cồn) là danh từ chỉ vật → câu chia ở dạng bị động.

Dịch: Khi được sử dụng làm chất sát trùng, cồn 70 phần trăm hiệu quả hơn cồn 100 phần trăm.
