Answer:
We don't truly.
Explanation:
What we do know is that they appeared around the same time on Earth:
Moles were discovered 54.8 million years ago
Rodents were discovered 54 million years ago.
If you want to compare it number wise, then moles came first.
They would still thrive. Plants only require sunlight and water to produce oxygen and glucose. The plant would just increase the concentration of oxygen in the terrarium over time.

No No and No to b,c,d. The answer is A.
Not all metals are malleable. Gold is especially so. Ductile is also one of gold's properties. It is an excellent conductor.
Ionic bonds guarantee a strong intra molecular bond. The ionic bond can dissolve in a solvent like water but not all of them do.
Non metal elements bonding with each other or with other non metals have very little power to be attracted to other molecules that are the same. The boiling points can be low.
The Covalent bonds are somewhat the same as the last group.
