The urea molecule (NH2CONH2) consists of 1 carbon atom, 1 oxygen atom, and 4 hydrogen atoms, and 2 nitrogen atoms.

1. Carbon has 4 valence electrons.
2. Oxygen has 6 valence electrons.
3. Hydrogen has 1 valence electron each, so 4 hydrogen atoms have 4*1 = 4 valence electrons.
4. Nitrogen has 5 valence electrons each, so 2 nitrogen atoms have 2*5 = 10 valence electrons.

Adding these up, the total number of valence electrons in a urea molecule is 4 (from C) + 6 (from O) + 4 (from H) + 10 (from N) = 24.

So, the answer is D. 24.
