A sentence has been given in indirect speech. Select the option that correctly expresses the sentence in direct speech.

The supervisor remarked that the technicians were adjusting to the updated protocol smoothly.

The correct option expressing the given sentence in direct speech is:
“The technicians are adjusting to the updated protocol smoothly,” remarked the supervisor.

Step-by-step Explanation:

To convert a sentence from indirect speech to direct speech, we follow these rules:

1. Reporting Verb and Speech Marks:
The reporting clause "The supervisor remarked that..." changes to introductory or concluding reporting speech with quotation marks surrounding the exact words spoken.

2. Tense Change:
When reporting speech is in the past tense (remarked), present continuous tense in direct speech changes to past continuous tense in indirect speech.
Here, the indirect speech uses past continuous: "were adjusting".
Therefore, in direct speech, it must be changed back to present continuous tense: "are adjusting".

3. Conjunction Removal:
The conjunction "that" used to introduce the reported clause in indirect speech is removed in direct speech.

Applying these steps:
Indirect: The supervisor remarked that the technicians were adjusting to the updated protocol smoothly.
Direct: “The technicians are adjusting to the updated protocol smoothly,” remarked the supervisor.
