37. In a solidary obligation, D1 and D2 bind themselves to give C1 and C2 P10,000. Which of the following is false?*

(A) C1 cannot renounce the obligation of D1 and D2 to pay P10,000 because the act is prejudicial to the other.

(B) C1 can renounce the obligation of D1 and D2 to pay P10,000 but C1 must give C2 P5,000.

(C) If C1 and C2 will renounce the obligation in favor of D1, the obligation is extinguished and D1 is to ask P5,000 from D2 representing the share of the latter.

(D) D1 and D2 can pay anyone of the creditors and if accepted the obligation is totally extinguished.

Brief explanation will do. Thanks!
