The tartaric acid has two chiral centers, practically it should give four stereoisomers. However, out of the four stereoisomers, two are identical. Therefore, there are three stereoisomers of tartaric acid.Two are enantiomers and one is achiral diastereomers (meso).
Therefore, the answer is (d) 2 chiral centers; 3 isomers.

Tartaric acid is a molecule with three stereoisomers, D-(-)-tartaric acid, L-(+)-tartaric acid, and meso-tartaric acid. The synthetic form of tartaric acid (the product produced in a laboratory) has an optical rotation of 0°. The meso isomer is also optically inactive. But, the melting points of the synthetic tartaric acid and the meso-tartaric acid are very different. (a) Is it possible that the synthetic form of tartaric acid is the meso isomer? Why or why not? (b) Why is the meso...

3. Diastereomers and Meso Forms. When a molecule has two or more stereogenic centers, stereoisomers that are not mirror images can exist; these are called diastereoisomers. Within this general class, there are special types of stereoisomers that are always optically inactive and are called meso forms. Construct a model with four different colored balls about a carbon center. Construct another identical to the first and verify this by the superimposition test. Now remove the same colored balls, blue (C from...
