In the layout of the Vijayanagara capital, the structure known as the "Queen's Bath" is located in the:

The correct option is Royal Centre.

Explanation

The layout of the Vijayanagara capital (Hampi) was organized into distinct functional zones, primarily the Sacred Centre, the Royal Centre, and the Urban Core. This zoning reflected the separation of ritual, political, and residential functions within the empire.

Detailed Analysis:

• Royal Centre: Located in the south-western part of the settlement, this area served as the seat of state power. It included over 60 temples but was distinctively characterized by palaces, administrative buildings, and secular structures. The Queen's Bath, along with other famous structures like the Lotus Mahal and the Elephant Stables, is situated here. The Queen's Bath is an Indo-Islamic style structure with a plain exterior and an ornate interior, surrounded by a moat.
• Sacred Centre: Situated on the rocky northern edge along the banks of the Tungabhadra River, this zone housed the most significant religious monuments, such as the Virupaksha Temple and the Vitthala Temple.
• Urban Core: This area contained the residences of the ordinary population, including traders and soldiers, and was distinct from the royal and sacred enclaves.

Key Takeaway:

The Royal Centre of Vijayanagara housed secular and administrative structures (e.g., Queen's Bath, Lotus Mahal), whereas the Sacred Centre was dedicated to major temple complexes along the river.
