Fill in the blank with the most appropriate option.
Nick : "Did you see a bird in the tree?"
Nick wonders _____ in the tree.
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 question starts with did, so if is used, you is changed to I.
The other options are wrong as that, had, see, and have seen can't be used.
The correct answer is A)If I saw a bird
