The correct answer is: A. limited to the amount of nominal value of capital held.
A co-operative society is a business owned and run by its members. The members of a co-operative society are usually people who share a common interest, such as farmers, consumers, or workers. The liability of members of a co-operative society is limited to the amount of nominal value of capital held. This means that members are only liable for the amount of money they have invested in the co-operative society.
Option B is incorrect because the liability of members of a co-operative society is not limited to the amount of paid up value of the capital held. Members are only liable for the amount of money they have invested in the co-operative society, regardless of whether or not they have paid up all of their shares.
Option C is incorrect because the liability of members of a co-operative society is not unlimited. Members are only liable for the amount of money they have invested in the co-operative society.
Option D is incorrect because the liability of members of a co-operative society is not limited or unlimited depending upon what the society has opted for it. The liability of members of a co-operative society is always limited to the amount of money they have invested in the co-operative society.
