Fill in the blank with the most appropriate option.
Jane said, "I shall help you."
Jane 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 D is correct as when we convert the given direct sentence to indirect speech, I is changed to she, will to would, and you to us.
The other options are wrong as helped, will help, helps, and had helped cannot be used.
The correct answer is D)she would help us
