Đáp án C
Ta thấy: “has created” – động từ đang chia theo thì hiện tại hoàn thành -> sau “and” động từ cần được chia theo thì hiện tại hoàn thành. Tuy nhiên, trong câu cần sửa “using them => used” – tạo ra một cụm tính từ bổ nghĩa cho danh từ "substances."
Dịch nghĩa: “Trong hàng nghìn năm, con người đã tạo ra các chất có mùi thơm từ gỗ, thảo mộc và hoa dùng làm nước hoa hoặc thuốc."
