For the second question, it is telling me "A" is not correct.

The conformations of (+)-epichlorohydrin (1), viewed along the CaCb bond, can be analyzed in exactly the same manner as the acyclic alkanes discussed in Chapter 4 (J. Phys. Chem. A 2000, 104, 6189-6196). Identify a staggered conformation for 1 viewed along the CaCb bond. Using the letters in the diagrams above, complete the labeling of all staggered conformations and all eclipsed conformations with the corresponding Newman projections. For conformations which are used more than once in the diagram, enter the letters in alphabetical order as a comma separated list (e.g."B,D")
