Answer: 2. it should be unstable structurally and chemically

A genetic material must: replicate itself, express itself (as Mendelian characters), and allow slow changes (mutations) for evolution. It must also be stable chemically and structurally.

So "it should be unstable" is the trait it should NOT have. That is why it is the exception.
