The Chair and Boat Conformations of Cyclohexane Are Shown Below

The chair and boat conformations of cyclohexane are shown below.Which statement best explains why the chair conformation is more stable than the boat conformation?

A) The hydrogen atoms in the chair conformation are all staggered,which minimizes the repulsion of the bonding electrons.
B) The carbon atoms in the chair conformation are all eclipsed,which provides for the ideal bond angle of 109.5°.
C) The carbon atoms in the chair conformation are closer together than in the boat conformation,which provides for stronger C-C bonds.
D) The hydrogen atoms in the chair conformation are closer together than in the boat conformation,which provides for stronger C-H bonds.
E) The C-C bonds in the chair conformation are all staggered,which maximizes the energy of the molecule.
