Directions: In the following question, a sentence with a underlined phrase is provided. Select the option that correctly replaces the underlined phrase to make the sentence grammatically and contextually correct. If the underlined phrase is correct as it is, select "No correction needed".

The hotel management announced yesterday that it will guarantee that all guest complaints are resolved within twenty-four hours.

The correct option is No correction needed.

Step-by-step explanation:
1. Subject-Pronoun Agreement:
The subject of the sentence is "The hotel management," which is a singular collective noun. The singular pronoun "it" correctly refers back to "hotel management."
2. Verb and Tense Usage:
The modal phrase "will guarantee" is grammatically sound and contextually appropriate to express an ongoing policy and future commitment made by the management.
3. Evaluation of Other Options:
• "it will have guarantee" is ungrammatical because the auxiliary phrase "will have" must be followed by a past participle ("guaranteed"), not the base form "guarantee."
• "they will guarantee" incorrectly uses the plural pronoun "they" to refer to the singular noun phrase "hotel management."
• "it will warranty" uses "warranty" awkwardly as a verb, whereas "guarantee" is the standard and correct term for formal assurances of service.
4. Conclusion:
Because the original underlined phrase is grammatically correct and conveys the intended meaning without error, no correction is required.
