Answer:
A) there is no contract because in this situation silence cannot be used to form a contract.
Step-by-step explanation:
Inez made an offer to Janice, and in order for an offer to be binding, it must be accepted by the other party (or parties). Only once the other party expressly accepts the offer, can a contract be formed. In this case, Janice did not accept Inez's offer, and an offer cannot force someone to do something. Both parties engaging in a contract must do so willingly and freely, if not, the contract is invalid due to duress.
If silence or the other party not responding could be considered acceptance, then anyone could send an email to Google and offer their professional services as CEO with a $100 million salary unless my offer is rejected in 5 minutes.
