The Mauryan capital of Pataliputra is associated with the archaeological remains of Kumrahar and Bulandibagh.

Option 1, Bulandibagh and Rajagriha, is incorrect. Rajagriha was the capital of the Magadha Empire before Pataliputra and is not directly associated with Pataliputra.

Option 2, Kumrahar and Mocharim, is also incorrect. Mocharim is not an archaeological site associated with Pataliputra.

Option 4, Kumrahar and Jalalgarh, is incorrect. Jalalgarh is not an archaeological site associated with Pataliputra.

The correct answer is option 3, Kumrahar and Bulandibagh. Kumrahar is an archaeological site in Patna, Bihar, where the remains of the ancient city of Pataliputra have been excavated. Bulandibagh is another archaeological site in Patna that is associated with the Mauryan capital. These remains provide valuable insights into the architecture, urban planning, and daily life of the Mauryan Empire.
