Correct option is C
Option (c) contains an error.
The subject of the clause “sugar and honey” is a compound subject joined by
and, so it requires a
plural verb. Therefore, the verb should be
taste, not
tastes. The other parts—
We all know,
very sweet—are correct in this context.
Grammatical rule used:
When two singular nouns are joined by
and and refer to different persons/things, the subject becomes
plural and takes a
plural verb (Subject–Verb Agreement).
Example:
“
Bread and jam taste delicious together.” (plural verb with compound subject)
Information booster / exceptions:
· If two nouns joined by
and denote
one idea/unit (e.g.,
bread and butter,
time and tide), a
singular verb may be used: “Bread and butter
is my breakfast.”
· If
each/every precedes the nouns (e.g.,
each boy and each girl), take a singular verb: “Each boy and each girl
was present.”
