Ann : "Is your sister good at English?"
Ann asked me ________________.
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 if is used as the question doesn't begin with a question word, asked is used as the introductory verb , the simple present tense is changed to simple past tense and your is changed to my.
The other options are wrong as if is not used, is, her sister can't be used, and if is missing.
The correct answer is B)if my sister was good at English
