Raj went to the Napa Valley Harvest Festival and stopped at Tina's booth where she was selling paintings of vineyards. Raj admired a painting of vineyards, which did not appear to be for sale. Raj said to Tina, "I will give you $200 if you give me that painting right now." Tina said nothing in response, but she gave Raj the painting, and Raj gave her $200 in cash.

1) bilateral and executed.
2) bilateral and executory.
3) unilateral and executed.
4) unilateral and executory
