Assertion (A): The reaction of 1 mol each of `(MeCH==O)` with glycerol `(overset(1)underset(OH)underset(|)CH_(2)-overset(2)underset(OH)underset(|)CH-overset(3)underset(OH)underset(|)CH_(2))` gives six separable isomers.
Reason (R ): Acetaldehydes react with 1-and 2-OH group of glycerol to form five-membered cyclic acetal. In the ring closure, two chiral centres are formed and thus we have pairs of enantiomers: cis and trans.
When acetaldehydes react with 1-and 3-OH groups, a six membered cyclic acetal is formed giving two disatereomeric products (cis and trans). These diastereomers are achiral.

A

If both (A) and (R ) true and (R ) is the correct explanation of (A).

B

If both (A) and (R ) are true but (R ) is not correct explanation of (A).

C

If (A) is true but (R ) is false.

D

If (A) is false but (R ) is true.
