Hey..
The correct option is D. i,e phosphorus.

Since Phosphorus is an essential component of phospholipids, nucleic acids, phosphoproteins (casein), high energy phosphate esters (ATP), hexose phosphates, creatine phosphate, it also provides strength to the exoskeletons of clams and oysters.

Basically the main structural compound is calcium carbonate which makes it hard and strong which provides defense from pests and predators, support, and in providing an attachment framework for musculature .

Hope it helps.

Option D i.e. Phosphorus is the right answer.

It is a highly reactive element and thus never found on earth as a free element.

The shell has calcium carbonate which is the prima compositional compound in it.

This calcium carbonate is also strengthened by phosphorus.

Thus, phosphorus invariably strengthens the exoskeletons of clams and oysters.
