Which of the following does not result into reconstitution of a partnership firm?

Correct option is B

A reconstitution of a partnership firm occurs when the existing agreement among partners changes, but the firm continues its business. Events leading to reconstitution include:
· Admission of a partner
· Retirement of a partner
· Death of a partner
· Change in profit-sharing ratio
These events cause the partnership agreement to change, but the firm continues.
However, dissolution of a partnership firm (option b) means the firm itself comes to an end — the business is closed, assets and liabilities are settled, and no continuation of partnership occurs. Therefore, it is not a reconstitution, but a complete termination of the firm.
Hence, the correct answer is: Option (b) is correct.
