Correct option is A
Option (a) contains the error.
Explanation of Error:
· The noun “kind” is singular, so the demonstrative adjective should be "this", not "these".
· OR, if we say “these kinds”, then both must be plural.
Correct sentence:
I do not like to read this kind of novels.
OR
I do not like to read these kinds of novels.
Grammatical Rule Used:
· Demonstrative adjectives must agree in number with the noun they modify.
· This/That → singular
· These/Those → plural
Grammar Booster:
In phrases like “this/that kind of”, the noun after "kind" is usually plural, but "kind" itself is singular and thus must take this/that.
