Choose the correct option to complete the sentence in indirect speech:
Dr. Paul said to John, "You have a viral infection."
Dr. Paul informed John that he____ a viral infection.
The two ways of relating what a person has said are 1)direct and 2)indirect (reported speech).In direct speech, the original speaker's exact words are repeated. In indirect/reported speech, the exact meaning is expressed but not necessarily using the original speaker's exact words. Pronouns and possessive adjectives usually change from first or second person to the third person except when the speaker is reporting his own words. Sometimes a noun can be inserted to avoid doubt.
When we turn direct questions and exclamations into indirect speech, they are converted to affirmative statement .( ? and ! is not used).
Option A is correct as the given direct speech is in the present perfect tense ans so past perfect tense is used. (Had)
The other options are wrong did has, had had, and have can't be used.
The correct answer is A) Had
