Answer:
Sid would not be liable if he had waited to buy Tech stock until "three weeks when the game was released".
Step-by-step explanation:
Sid, by finding out about the development of a new and exciting video game, and then acting on that information by purchasing Tech stock, and also informing his friend Uri to do the same, has committed illegal insider trading.
He used non-public information (that had not yet been made available to the public) to make extra profit for himself and his friend, Uri.
If Sid had waited until the information became public three weeks later, before purchasing Tech stock, then he would not be liable for illegal insider trading.
