Find the Correct Statement About Cis-Trans Isomers

Multiple Choice

A) Cis-trans isomers are diastereomers and occur because the rotation around a C≡C bond is very restricted.
B) Cis-trans isomers are enantiomers and occur because the rotation around a C=C bond is very restricted.
C) Cis-trans isomers are diastereomers and occur because the rotation around a C=C bond is very restricted.
D) Cis-trans isomers are superimposable constitutional isomers of substituted alkenes formed around a C=C bond.
E) Cis-trans isomers are chiral molecules and occur because the rotation around a C=C bond is very restricted.
