Oxidation of A with $mathrm{HNO_3/H_2O}$ provides the product (s), which is (are) 
A
A(a)Optically active as it is racemic mixture
(b)Optically inactive as it is meso
(c)Optically active as it is a single diastereomer
(d)Optically active as it is a single enantiomer
Answer
Answer: B ✓ checked by 4AB · confidence high
Explanation
HNO₃ oxidises both ends to COOH. The zig-zag aldotetrose with its two OH groups on opposite wedge/hash gives the tartaric acid with an internal mirror plane: meso, optically inactive (b).
