Hello Surya, 

For applying to AP Polycet, you need to have Andhra Pradesh as your domicile state. Since Telengana separated from Andhra Pradesh your domicile will not be considered under Andhra Pradesh. Telengana has its own state POLYCET exam called TS POLYCET. Your daughter can sit for this exam from Telengana.
