C. The greater the energy of the level, the farther away it is from the nucleus.

Explanation:

A is wrong because electrons can either move to higher energy levels (if they gain energy) or to lower energy levels (if they lose energy).

B is wrong because the second energy level holds a maximum of six electrons.

C is the right choice because as we move away from the nucleus, the greater the energy of the level.

D is wrong because in its outermost energy level, oxygen has 6 valence electrons. Oxygen has 8 electrons, its distribution is: 2, 6.
