Explanation:

- Option 1: Rights: Partners have the right to participate in management, share profits, and access business information. However, attending to something implies a duty or obligation rather than a right.

- Option 2: Meetings: While partners attend meetings, the conduct of the business entails more than just attending meetings.

- Option 3: Capital: Capital refers to the financial contribution of partners. It doesn't pertain to the conduct of business activities themselves.

- Option 4: Duties: Partners have various duties, including acting in good faith and managing business affairs responsibly. Attending diligently to the conduct of the business clearly relates to fulfilling duties.
