Which one of the following is located in the Bastar region?

Indravati National Park is located in Bijapur/Dantewada area of Chhattisgarh and is identified as a major protected area in the Bastar region, making it the correct choice here [1]. Bandhavgarh National Park lies in Madhya Pradesh and therefore is not in Bastar [2]. Dandeli (Dandeli Wildlife/Anshi region) is situated in Karnataka’s Western Ghats, not in Chhattisgarh. Rajaji National Park is near Haridwar in Uttarakhand and is likewise outside the Bastar area [3]. Indravati, named after the Indravati River, is a national park and tiger reserve in southern Chhattisgarh and is commonly associated with the Bastar forest landscape, so option 4 (Indravati) is correct.
