The correct answer is A. Business.
Rishabhanatha was the first Tirthankara of Jainism and is considered to be the founder of the religion. He is said to have lived in the 9th century BCE and is credited with teaching the principles of non-violence, non-attachment, and asceticism.
According to Jain texts, Rishabhanatha gave five karmas before starting an era: agriculture, ink, sword, craft, and service. Business is not one of the five karmas that Rishabhanatha gave.
Agriculture is the cultivation of plants and crops. Ink is a liquid or paste used for writing or printing. A sword is a weapon with a long, sharp blade. Craft is the skill of making things by hand. Service is the act of helping or doing something for someone else.
Business is the activity of making and selling goods or services in exchange for money. It is a way of making a living and can be a very profitable enterprise. However, it can also be a very stressful and demanding occupation.
Rishabhanatha did not give the karma of business because he believed that it was a way of accumulating wealth and power, which he saw as obstacles to spiritual progress. He believed that people should focus on their inner development and not on material possessions.
In conclusion, the correct answer to the question “Before starting of an Era, what was the last karma given by Rishabhanatha other than agriculture, ink, sword, craft and service?” is A. Business.
