Hint: In order to answer this question, to know the correct option regarding diastereoisomers, we should go through the explanation of diastereoisomers. And then we will explain more about the diastereoisomers.
Complete answer: Diastereomers are a type of stereoisomer that occurs when two or more stereoisomers of a compound have different configurations and are not mirror images of each other. Hence, $( + )$ tartaric acid and meso tartaric acid are diastereo-isomers. Diastereomers are nonsuperimposable, non-mirror representations of compounds that have the same molecular formula and sequence of bonded elements. Stereoisomers are enantiomers and diastereomers that come under the wider definition of isomerism, which often includes at least two species being compared. Non-mirror image non-identical stereoisomers are known as diastereomers. As a result, they happen when two or more stereoisomers of the same compound have different configurations at one or more (but not all) of the equivalent (related) stereocenters and aren't mirror copies of each other.
Hence, the correct option is (A).
Note: Tartaric acid is a white crystalline dicarboxylic acid that can be present in a variety of plants, including tamarinds and grapes. Following oral administration, tartaric acid interacts with sodium bicarbonate to produce carbon dioxide.
