Answer:please refer to the explanation section
Explanation:
Silence doesnot constitute legal consent. The court of law does not recognize silence as the acknowledgement of the contract unless one party gives the impression that his or her silence means acceptance/acknowledgement. The silence of one party may be interpreted as consent provided the party is well aware of his or her rights at the time the contract is negotiated and his or her silence is voluntary.
Marisol was present when charlie negotiated the sale the Bicycle, He heard the entire conversation and he knew he had the right to object but chose not to. He can speak for him self thus we can conclude that his silence was voluntary, with that being said his silence may be interpreted as consent to the contract therefore he is bound by the contract
