Rewrite the sentence in indirect speech.
Anitha said, "I've been learning Bharatanatyam for the past six months."

Correct option is A

The correct option is (a) Anitha said that she had been learning Bharatanatyam for the past six months.
Tense change: "I’ve been learning" (present perfect continuous) changes to "had been learning" (past perfect continuous) in indirect speech.
Pronoun change: "I" becomes "she" to reflect Anitha in the third person.
Time clause change: The time expression "for the past six months" remains unchanged as it refers to a specific duration.
Reporting verb change: "Said" remains unchanged.
Corrected sentence: Anitha said that she had been learning Bharatanatyam for the past six months.
