Why does molecular polarity occur?
A molecule's polarity is caused when the two nuclei making up the molecule are different sizes.
Polarity is caused when electrons in a covalent bond are not equally shared.
Polarity is caused when electrons are taken by one atom in an ionic bond.
Polarity is caused when electrons are shared equally in a covalent bond.

Polarity occurs when the electrons are not shared equally in a covalent bond.

Explanation:

B. Polarity is caused when electrons in a covalent bond are not equally shared.

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

the answer would be a
