65. S sold to B a specific car for P300,000 and promised to deliver on December 1, 2020. The next day, after the sale was made, she sold the same car to X and delivered it to him (X) on the same day. If no delivery is made by S to B on December 1, 2020, which of the following is correct?

(A) S is not in default because there was no demand.

(B) B can cancel the contract between S and X because the contract of S and B was perfected ahead.

(C) S is liable to B for the value of the car.

(D) S is in default, even if there was no demand. Hence, she will answer for damages

A brief explanation will do. Thanks!
