Fill in the blank with the most appropriate option.
"You must do what you are told".
He said __________________.
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 E is correct as when we convert the given direct speech to indirect speech , must is changed to had to, you to she, you is changed to she, and are to was.
The other options are wrong as I, what, had, and must not can't be used.
The correct answer is E)she had to do what she was told
