Step-by-step explanation:
The snake you spotted in the drain near your hostel in Kharagpur, West Bengal, India could not be accurately identified without a clear image or description. However, I can provide you with some general information that may help. In India, there are several venomous snakes, including the Indian Cobra (Naja naja), Russell's viper (Daboia russelii), and the Common krait (Bungarus caeruleus). These snakes are highly venomous and can pose a threat to humans. It is always important to exercise caution and avoid handling or approaching any snake if you are unsure about its species and venomosity.
