In each sentence, a part is given in bold, which may or may not be grammatically correct. If incorrect, replace it with the best alternative among the given options. If correct, choose “No correction required” as your answer choice.

The all-inclusive resort trip seemed heavenly, with all guests relaxed and have a well time.

Correct option is C

The correct option is: “ relaxed and having a great”.
This option is the correct answer. It uses the correct adjective "relaxed" to describe the guests and the correct form "having a great" to indicate that they are enjoying themselves during the trip.
Incorrect options:
(a) relax and have a great
This option is grammatically incorrect because it uses the base form of the verb "relax" instead of the correct form "relaxed." The correct form should be "relaxed and having a great" to maintain subject-verb agreement in the sentence.
(b) relaxation and having a good
This option changes the meaning of the sentence. It uses the noun "relaxation," which refers to the state of being relaxed, but the correct form should be ‘relaxed’ which is an adjective. The correct form should be "relaxed and having a good"
(d) relax and having a well
This option is grammatically incorrect. It uses the base form of the verb "relax" instead of the correct form "relaxed," and it uses the adjective "well" instead of the correct adjective "great" to describe the time the guests are having. ‘Well’ as an adjective means in good health; free or recovered from illness.
In conclusion, option " relaxed and having a great" is the best alternative that fits both grammatically and contextually with the sentence. It describes the guests at the all-inclusive resort trip as being in a relaxed state and having a great time.
