What does the law say about option contract?

Art. 1479. A promise to buy and sell a determinate thing for a price certain is reciprocally demandable.

An accepted unilateral promise to buy or to sell a determinate thing for a price certain is binding upon the promissor if the promise is supported by a consideration distinct from the price. (1451a)

*The second paragraph in this provision is referred to as option. This unilateral promise to sell or buy a determinate thing does not bind the promissor though accepted until a consideration distinct from the price supports this perfected contract.

Example would be when A promises to sell to B a car which B accepts. S is not bound to sell his car if there is not promise on the part of B to buy. However if the promise is supported by a consideration distinct from the price, as when B paid or promised to pay a sum of money to A for giving him the right to buy the car whenever he pleases during a certain period of time, then a perfected option contract is entered in to.
