The correct answer is OPTION 2 - "Where are you going?" asked the security guard.

To convert indirect speech back into direct speech, we look at three main components:

• The Reporting Verb: "Enquired" becomes "asked" in the direct form.

• The Pronoun: In indirect speech, "we" refers to the people being questioned. When moving to direct speech, this typically changes to "you" to reflect the guard speaking directly to the group.

• The Tense and Word Order: The indirect phrase "where we were going" (past continuous) reverts to the present continuous "Where are you going?" for the direct question. Notice that the word order also flips from subject + verb (we were) to verb + subject (are you) to form a proper question.

• Option 1: Adds the word "all," which wasn't in the original sentence.

• Option 2: Corrects the tense, uses the proper question structure, and maintains the original meaning perfectly.

• Option 3: Uses incorrect grammar ("Where you all are..."). In a direct question, the auxiliary verb must come before the subject.

• Option 4: Uses a completely non-standard sentence structure.
