The Dharmashastras and Dharmasutras
The Dharmashastras and Dharmasutras are ancient texts that provide guidelines and principles for leading a righteous and ethical life according to Hindu dharma. These texts are considered authoritative sources of Hindu law and cover various aspects of human life, including social, moral, and legal responsibilities.

Ideal Occupations
In these texts, the ideal occupations were classified into different categories based on the varna system, which is a social stratification system prevalent in ancient India. According to the varna system, society was divided into four major varnas or classes:

1. Brahmins: The Brahmins were the highest varna and were responsible for intellectual and spiritual pursuits. Their ideal occupation was the study and teaching of the Vedas, performing rituals, and offering guidance and counseling to the community.

2. Kshatriyas: The Kshatriyas were the warrior class and were responsible for protecting the society and maintaining law and order. Their ideal occupation was to serve as rulers, warriors, and administrators. They were expected to lead armies, govern kingdoms, and defend their people.

3. Vaishyas: The Vaishyas were the merchants and farmers who engaged in trade, agriculture, and animal husbandry. Their ideal occupation was to engage in business activities, farming, and cattle rearing. They played a crucial role in the economic development of society.

4. Shudras: The Shudras were the laborers and servants who provided various services to the higher varnas. Their ideal occupation was to serve the other varnas and fulfill their needs. They were expected to perform menial tasks and support the functioning of society.

Division of Ideal Occupations
The Dharmashastras and Dharmasutras divided the ideal occupations into four categories based on the varna system. These categories are:

1. Brahmanya: This category included the occupations suitable for Brahmins, such as teaching, studying, performing rituals, and offering guidance.

2. Kshatriya: This category included the occupations suitable for Kshatriyas, such as ruling, administration, military service, and defense.

3. Vaishya: This category included the occupations suitable for Vaishyas, such as trade, agriculture, cattle rearing, and entrepreneurship.

4. Shudra: This category included the occupations suitable for Shudras, such as labor, service, and supporting the functioning of society.

Therefore, the correct answer is option 'C' - Four, as the Dharmashastras and Dharmasutras divided the ideal occupations into four categories based on the varna system.
