Name of the group-16 element which shows maximum catenation.

Solution
The correct option is A Sulphur
The greater the element-element bond strength, the higher is the tendency towards catenation. As the size increases from S to Te, the bond dissociation energy decreases. O - O bond energy is, however, smaller than that of S-S because of inter electronic repulsions within the smaller size of oxygen atoms.
Thus, sulphur has a maximum tendency towards catenation.
