Solution

The grammatical error is in the segment "developing countries are".

Key points:

• Subject-verb agreement: The subject of the sentence is "one," which is singular, so the verb must also be singular.

• The phrase "of the developing countries" is a prepositional phrase modifying "one" and does not change the number of the subject.

Corrected sentence:

One of the developing countries is in favor of this agreement.

Additional note:

• The phrase "in the favor of" is not idiomatic; use "in favor of."

• Example of correct usage with "one of": One of the musicians was selected to sing in the award show.
