Lena said, "Where have you been yesterday?"
Lena asked _________________________
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 the question word where, so, where is repeated, you is changed to she, yesterday to the day before and the present perfect tense to past perfect tense.
The other options are wrong as yesterday, was, could be, and hasn't been can't be used.
The correct answer is A)where she had been the day before.
