The correct answer option is (b) Rajagriha 🟢. Detailed Explanation 🟢 Why (b) is correct: Rajagriha (modern-day Rajgir, Bihar) served as the earliest capital of the ancient Magadha kingdom. Geographically surrounded by five protective hills, it formed a natural stone fortress that made it virtually impregnable to enemy invasions. It was originally called Girivraja and remained the political epicenter under early Magadhan rulers like King Bimbisara and King Ajatashatru. ❌ Why (a) is incorrect: Pataliputra (modern-day Patna) became the capital of Magadha much later. It was founded as a fortified village (Patali-grama) by Ajatashatru, but his successor Udayin formally shifted the permanent imperial capital from Rajagriha to Pataliputra due to its strategic riverine location. ❌ Why (c) is incorrect: Champa was the capital of the neighboring Anga Mahajanapada (located in the modern Bhagalpur and Munger regions of Bihar). It was subsequently annexed into Magadha by King Bimbisara. ❌ Why (d) is incorrect: Vaishali served as the capital of the Vrijji Mahajanapada (the world's earliest republic). It briefly became the capital of Magadha during the reign of King Shishunaga, but was not the primary early seat of Magadhan power.
