The correct answer is B. Glucose has 6 carbon molecules.

Glucose is a simple sugar that is found in the blood and is used by the body for energy. It is a six-carbon sugar, which means that it has six carbon atoms in its molecular structure. The molecular formula of glucose is C6H12O6.

The other options are incorrect. Option A is incorrect because glucose has 6 carbon atoms, not 10. Option C is incorrect because glucose has 6 carbon atoms, not 5. Option D is incorrect because glucose has 6 carbon atoms, not 8.

I hope this helps!
