Sam, a store owner, sold a gallon of rat poison to Ben for P1,000.00. Ben intended to pour the poison in the fishpond of Doray, his enemy, to kill all the fishes therein. The sale of the rat poison is:

a) Valid provided Ben does not pursue his motive to kill the fish in the fishpond of Doray.

b)Valid even if B pursues his motive to kill the fish in the fishpond of Doray.

c)Void as it is immaterial whether or not Ben kills the fish in the fishpond of Doray since Ben's motive is void.

d)Void if Ben pursues his motive to kill the fish in the fishpond of Doray.
