The octet rule maintains that all molecules must have a full outer shell, and it wants to give that one electron away, because it'd be easier than gaining seven more. So, it'd be B :)
The atomic number of sodium is 11. It is represented as Na. Its outermost shell contains only one electron. The electronic configuration of sodium is 1s²2s²2p⁶3s¹. According to the octet rule, the atoms are organised in such a way that they have a valance electrons in their valance shells so that they acquire same electronic configuration as noble gases.
As per octet rule, sodium wants to give up an electron so as to acquire the stable configuration i.e. 1s²2s²2p⁶ or [Ne]. Ne is neon and it is a noble gas. So, sodium give up an electron and acquire the stable electronic configuration of Neon. Hence, the correct option is (B).
Vitamic C or ascorbic acid acts as a cofactor in the process of collagen synthesis. It has been shown that lack of vitamin C leads to the impaired collagen synthesis. Beside that activity, vitamin C has many other funtions within organism:
antioxidant
cofactor in other enzymes
involved in wound healing (repair of tissue)
involved in the production of some neurotransmitters...
