A bond will form so the outermost energy level of an atom will have .

valence electrons

Explanation:

The electrons on the outermost energy level of the atom are called valence electrons. The valence electrons are involved in bonding one atom to another. The attraction of each atom's nucleus for the valence electrons of the other atom pulls the atoms together.

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be
