Explanation: To understand the context of the statements, let's break down each one:
1. **Mumbai is named after a local deity Mumbadevi**: Mumbai, the capital city of Maharashtra, is named after the local deity Mumbadevi. Mumbadevi is the goddess of the city, and the name "Mumbai" is derived from "Mumba," which is an incarnation of the goddess Mumbadevi. The city was originally a collection of seven islands, and the name "Mumbai" reflects the local cultural and religious heritage.
2. **The Ryotwari system was introduced in Madras and Bombay presidencies**: The Ryotwari system was a land revenue system introduced by the British in India. It was implemented in the Madras and Bombay presidencies. Under this system, the land revenue was directly collected from the cultivators (ryots) by the government. This system was different from the Zamindari and Mahalwari systems, which were implemented in other parts of India. The Ryotwari system aimed to simplify the revenue collection process and reduce the role of intermediaries between the government and the cultivators.
3. **BSE stands for Bombay Stock Exchange**: The Bombay Stock Exchange (BSE) is one of the oldest and largest stock exchanges in Asia. It was established in 1875 and is located in Mumbai. The BSE is a significant financial institution in India, providing a platform for trading stocks, bonds, and other financial instruments. The name "BSE" is a direct abbreviation of "Bombay Stock Exchange," reflecting the historical and economic significance of Mumbai in the Indian financial sector.
