d hydrogen
attempt 1 of 2 submit

Explanation:

Carbohydrates are organic compounds. Their general formula is approximately \( C_n(H_2O)_m \), which shows they contain carbon (C), hydrogen (H), and oxygen (O). Nitrogen (N) is not a typical element in simple carbohydrates (though some complex derivatives might have it, but the basic ones don't). So options B (carbon), C (oxygen), and D (hydrogen) are correct. Option A (nitrogen) is incorrect for basic carbohydrates.

Answer:

B. carbon, C. oxygen, D. hydrogen
