Answer: correct option will D.

Step-by-step explanation:

Calcium belongs to the group 2 i.e. of alkaline earth metals in periodic table. electronic configuration of calcium is
[Ar]4s^2 .

So in order to attain noble gas configuration calcium will loose its two electrons during chemical bond formation.

$Ca\rightarrow Ca^(2+)+2e^-$

Sulfur is a non metal which forms negatively charged ion so as to complete ts octet during chemical bond formation.

Helium is a noble gas with fully filled electronic configuration.

Carbon forms bond which is covalent in nature.
