Arrange the following sentences - a) To the actual cost of the service b) In…

Correct sentence: Marketing cost is no longer in rational proportion to the actual cost of the service.

Explanation: The chosen word order places the subject first, then the verb phrase with negation, followed by the complement and the prepositional phrase, which yields a grammatical and meaningful sentence.

• Subject: "Marketing cost"

• Verb phrase with negation: "is no longer" ("no longer" modifies the verb and should follow the auxiliary/main verb)

• Complement: "in rational proportion"

• Prepositional phrase: "to the actual cost of the service"

Note: The original solution incorrectly used "are" in one place; with the given singular phrase "Marketing cost" the correct verb is "is". If the subject were plural ("Marketing costs"), then "are" would be appropriate.
