In the following questions, a few sentences are given. Identify the sentences that are grammatically and contextually correct.

(I) The team has worked really hard and deserves all of the praise they are receiving.

(II) She was excited to start her new job, but her nervousness was affecting her confidence.

(III) Each of the students were required to submit their projects before the deadline.

The correct option is Both (I) and (II).

Let's analyze each sentence step-by-step to check for grammatical and contextual correctness:

Sentence (I): "The team has worked really hard and deserves all of the praise they are receiving."
- Subject-Verb Agreement: "The team" is a collective noun treated as a singular subject here, which correctly takes the singular verbs "has worked" and "deserves".
- Context/Grammar: The usage of "all of the praise they are receiving" is natural, contextually clear, and grammatically correct.
- Therefore, sentence (I) is correct.

Sentence (II): "She was excited to start her new job, but her nervousness was affecting her confidence."
- Structure & Tense: The sentence uses past continuous ("was affecting") and past simple ("was excited") consistently.
- Grammar & Context: The conjunction "but" correctly links the two contrasting ideas. All words are used in their proper context and forms.
- Therefore, sentence (II) is correct.

Sentence (III): "Each of the students were required to submit their projects before the deadline."
- Subject-Verb Agreement Error: The subject of the sentence is "Each", which is a singular indefinite pronoun. Therefore, it requires a singular verb ("was required") rather than the plural verb "were required".
- Correction: "Each of the students was required to submit their project before the deadline."
- Therefore, sentence (III) is incorrect.

Since sentences (I) and (II) are correct while sentence (III) contains a subject-verb agreement error, the correct choice is Both (I) and (II).
