Which of the following statements are correct?

The correct options are
A Diastereomers have different physical properties and similar but not identical chemical properties
B Enantiomers have the same physical and chemical properties but different physiological properties
C Polarimeter is used in measuring the optical rotation of a compound.
(A) Diastereomers have different physical properties (such as melting and boiling points) and similar but not identical chemical properties (such as rates of reaction, selectivity and specificity etc).
(B) Enantiomers have the same physical and chemical properties (such as melting and boiling points) but different physiological properties (such as one enantiomer acts as a drug and the other enantiomer is toxic).
(C) Polarimeter is used in measuring the optical rotation of a compound. A polarimeter is a scientific instrument used to measure the angle of rotation caused by passing polarized light through an optically active substance.
(D) Both organic and inorganic molecules (coordination compounds) show optical isomerism.
