The correct answer is A. 1, 2 and 4.
A partnership is dissolved when the partners agree that the firm should be dissolved, when the business becomes illegal, when a partner gives notice of dissolution in case of partnership at will, or when the court orders dissolution.
Option 1 is correct because the partners can agree to dissolve the partnership at any time.
Option 2 is correct because a partnership is dissolved when the business becomes illegal. For example, if the partnership is involved in illegal activities, the partnership will be dissolved.
Option 3 is correct because a partnership at will can be dissolved by any partner giving notice to the other partners.
Option 4 is correct because a partnership can be dissolved by a court order. For example, if the partners are unable to agree on how to manage the partnership, the court may order the partnership to be dissolved.
I hope this helps!
