Option (ग) 'आत्मीय' is the correct answer because the provided text clearly states that Lata Mangeshkar had a very good relationship with the chorus girls. She mentions that they were like family to her ('वो बिल्कुल मेरे घर जैसी थीं'), they frequently visited each other's homes ('सबका ही घर में आना-जाना होता था'), and she would sit on the floor with them during recordings and chat. These details reflect an intimate, familial, and affectionate bond, not a formal, purely professional, or competitive one.
