**The Ruling Class in South India: The Arasars**

The correct answer to the question is option 'B', the Arasars were the ruling class in South India. Let's delve into the details to understand why this is the correct answer.

**Introduction to the Arasars:**
The Arasars, also known as the Arasu or Arasan, were a powerful and influential feudal ruling class in the southern regions of India, particularly in the states of Tamil Nadu and Kerala. The term "Arasar" translates to "king" or "ruler" in the Tamil language.

**Historical Significance:**
The Arasars played a significant role in the history of South India. They were the feudal lords who held positions of power and authority, ruling over the territories under their control. The Arasars were responsible for maintaining law and order, collecting taxes, and dispensing justice within their domains.

**Feudal System and Administration:**
The Arasars formed the upper echelon of the feudal system prevalent in South India during ancient and medieval times. They held extensive lands and exercised control over the lower classes, including peasants, artisans, and other laborers who worked on their lands.

**Land Ownership and Revenue Collection:**
The Arasars were primarily landowners who possessed vast agricultural estates. They derived their wealth and power from the produce of these lands and collected revenue from the peasants who cultivated them. This revenue collection formed a significant part of their income and strengthened their position as rulers.

**Military and Political Influence:**
Apart from their administrative duties, the Arasars also maintained a well-equipped military force. This army served to protect their territories from external threats and maintain their authority within their domains. The Arasars often engaged in political alliances, rivalries, and conflicts with neighboring rulers and dynasties, further establishing their significance as the ruling class.

**Legacy and Decline:**
The influence of the Arasars gradually diminished with the advent of the British colonial rule in India. The British system of governance replaced the traditional feudal system, leading to the decline of the Arasars' power and authority. However, their historical significance as the ruling class in South India cannot be undermined.

In conclusion, the Arasars were the ruling class in South India, holding positions of power and authority over vast territories. They played a crucial role in the administration, revenue collection, and maintenance of law and order in the region. While their influence declined with the advent of British colonial rule, their legacy as the ruling class of South India remains significant.
