1024. When an obligation is alternative the debtor is discharged by giving or doing one of the 2 things to which the obligation refers; but he cannot compel the creditor to accept a part of one and a part of the other.
1025. The option belongs to the debtor unless it has been expressly granted to the creditor.
1026. An obligation is simple although contracted in an alternative form, if one of the two things promised could not be the object of the obligation.
1027. If one of the things promised in an alternative obligation should perish, or can no longer be delivered, whether or not owing to the fault of the debtor, its value cannot be offered instead, and the obligation becomes applicable solely to the other.
If both things have perished or can no longer be delivered, and the debtor be in fault with respect to one of them, he or she must pay the value of that which remained last.
1028. If the choice of alternatives rests with the creditor, when one of the 2 things cannot be delivered, and there is no fault on the part of the debtor, the creditor must take the other; but when the debtor is in fault, the creditor may demand that which remains or the value of the other.
When neither thing can be delivered and the debtor is in fault in respect of either or both, the creditor may demand the value of either.
1029. If both things have perished, the obligation is extinguished in the cases and subject to the conditions provided in article 1130.
1030. The rules contained in the articles of this section apply to cases where the alternative obligation comprises more than 2 things, or has for its object to do or not to do some thing.
