Which of the following statements most accurately describes the stereochemistry between the various cyclohexanes?

• A. Cis-1,2-dichlorocyclohexane and trans-1,2-dichlorocyclohexane rotate plane-polarized light in opposite directions, and together in equal proportions form a racemic mixture
• B. The diaxial and diequatorial forms of trans-1,3-dichlorohexane can be separated by their differing physical properties
• C. Only cis-1,4-dichlorocyclohexane is achiral due to a plane of symmetry, and cis-1,4-dichlorocyclohexane is diastereomeric to trans-1,4-dichlorocyclohexane
• D. The conformational isomers of trans-1,2-dichlorocyclohexane are enantiomers, which are not interconvertible, but resolvable
