Select the option that expresses the given sentence in Direct to Indirect Speech.
He said, "I have completed the task."

Correct option is D

The correct indirect speech is (d) He said that he had completed the task.
Explanation: The reporting verb said is in the past; therefore, in indirect speech the present perfect have completed changes to past perfect had completed. The first-person pronoun I changes to he to match the subject of the reporting clause.
Rules of conversion:
· Tense backshift with a past reporting verb: Present perfect → Past perfect.
· Pronoun change as per context: I → he/she.
· Remove quotation marks; use a conjunction ( that) for statements.
· Example: Direct: She said, “I have finished my work.” → Indirect: She said that she had finished her work.
