For the sentence given, choose from the options provided, the most appropriate sentence in reported speech.
She said, "The receptionist directed me to the wrong room."

Correct option is D

The correct option is (d) She said that the receptionist had directed her to the wrong room.

Explanation:
The given sentence is in Direct Speech. While converting it into Indirect (Reported) Speech, the following rules apply:

Rules Applied in Conversion (Direct → Indirect):

• Reporting verb: said is retained as it is (no indirect object, so said that is used).
• Conjunction: that is added after the reporting verb.
• Tense Change: Simple Past (directed) → Past Perfect (had directed), since the reporting verb said is in the past tense.
• Pronoun Change: me → her (the pronoun changes from first person to third person, referring to the speaker).
• Quotation marks are removed.

• (a) the receptionist directed her – Tense is not changed; directed should become had directed in reported speech.
• (b) she had been directed – Changes the sentence to passive voice unnecessarily and alters the original meaning and focus.
• (c) she was directed to the wrong room – Omits the agent (the receptionist) and changes the voice; does not faithfully report the original statement.
