Examine the model of vitamin C and determine the molecular formula. In the model shown, the black sphere = C atom, o sphere = H atom, o Sphere = O atom. 

 

The molecular mass of vitamin C is 176.14 grams per mol.
Vitamin C has the chemical formula ${\mathrm{C}}_6{\mathrm{H}}_8{\mathrm{O}}_6$ and a molecular mass of 176.14 grams per mol.

Vitamin C is necessary for the creation of collagen, a protein crucial for the development of connective tissue and for the healing of wounds. Antioxidants defend against harm from unstable chemicals known as free radicals. Additionally, the vitamin aids in boosting the immune system.

Hence, the option B is correct.
