d

Explanation:

To determine the structure of urea (\(CH_4N_2O\)), we analyze the atoms: 1 C, 4 H, 2 N, 1 O.

• Option A: Fewer N atoms (no blue, likely N) → incorrect.
• Option B: Only C and H (no N/O) → incorrect (alkane).
• Option C: Contains 1 C (gray), 2 N (blue), 1 O (red), 4 H (white) → matches \(CH_4N_2O\) (urea’s structure: \(H_2NCONH_2\)).
• Option D: Complex, more atoms → incorrect.

Answer:

C. The structure with one gray (C), two blue (N), one red (O), and four white (H) atoms.
