Select the option that expresses the given sentence in direct speech.
The teacher told the students that she had waited for them for about 5 minutes before leaving the class.

Correct option is A

Given Sentence:
The teacher told the students that she had waited for them for about 5 minutes before leaving the class.
Steps to Convert to Direct Speech:
Identify the Reporting Verb:
The reporting verb is "told." In direct speech, this becomes "said to" when followed by the person being addressed (in this case, "the students").
Convert the Reported Speech:
The reported clause "that she had waited for them for about 5 minutes before leaving the class" is converted to the direct speech: "I waited for you for about 5 minutes before leaving the class."
Pronoun Changes:
"She" changes to "I" because in direct speech, the teacher is speaking about herself.
"Them" changes to "you" as the teacher is directly addressing the students.
Tense Changes:
The past perfect tense "had waited" changes to the past simple tense "waited" because in direct speech, the original words of the speaker would typically use past simple tense.
The use of "before" remains unchanged as it correctly indicates the sequence of events.
Quotation Marks:
The teacher's exact words are placed within quotation marks.
Correct Answer:
(a) The teacher said to the students, “I waited for you for about 5 minutes before leaving the class.”
