Answer: Option A and B.
Step-by-step explanation: Limited liability concept originates from the concept of separate legal entity. As per separate legal entity the owner of the company and the company itself are two different entities.
Thus,in case of any default or liquidation of the company, owner will be liable to pay only to the extent of his investment in the company. The personal assets of the owner could not be taken into consideration for the purpose of repayment.
Hence, from the above we can conclude that the correct option is A and B.
