When such a nest is destroyed, the adders wander, never spending consecutive days in the same place, until they come across another nest of the Silver-spotted Skipper insect. Clearly, the Lichtenstein night adder does not know how to make nests of its own.

Which of the following, if true, most strengthens the argument?

A. Many sub-species of the adder are known to make their own nests from scratch.
B. In the summer months, the Lichtenstein night adder snake prefers sleeping by hanging from a tree and not staying anywhere on the ground level.
C. In Nigram and Tenitol, countries where Silver-spotted Skippers are not found, the Lichtenstein night adder makes its home in the nests of Cicada insects.
D. The two species of snakes that are closely related to the Lichtenstein night adder species do not live in nests at all.
E. There are no significant differences between the nest of a Silver-spotted Skipper insect and that of some species of adder snakes that make nests of their own.

OA - C

this option seems to be strengthening the argument not weakening it. I selected D
reasoning for D is that no species of such snakes believe in concept of their own nest. others cant be the option even remotely.

I have a question here or rather an alternative reasoning. Suppose i know how to build house, but i can buy one too. and if i bought one then is it means that i can't build one. i am still not convinced that This option is really making sure that he don't know how to make a nest.
