The question asks us to match pairs of compounds (List-I) with their corresponding type of isomers (List-II). Let's go through each option:
Therefore, the correct matching is:
A-III, B-I, C-IV, D-II
Consider the reaction given below:

\(\text{A gives positive Fehling's test. Choose the correct relation}\).
Write the correct order of rate of reaction of following compounds with $PhN_2Cl$
P: $N,N$-dimethylaniline
Q: $N,N$-dimethyl-3-methylaniline
R: $N,N$-dimethyl-2,6-dimethylaniline
Most preferred site for electrophilic substitution in above example?
(Note: The molecule contains a nitrogen-containing ring and a carbonyl-containing ring, labels are U, S, R, P).
