Fill in the blank with the most appropriate option.
He says "What do the pupils study?"
He asks _____________________
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 B is correct as when we convert the given direct question to indirect speech the question word is repeated, asks is used a the introductory verb, and the tense is not changed as 'says' is used in the direct speech.
The other options are wrong as do, studied, have studied, and something can't be used.
The correct answer is B)what the pupils study.
