You are stopped at a multi-lane intersection, waiting for a green light. When the light turns green, the car next to you tries to accelerate quickly and starts moving into your lane. You should:

A. Take your foot off the gas pedal and give the other driver room to enter your lane in front of you.
B. Ignore the other car, and accelerate the way you normally do.
C. Accelerate as you normally do, and honk your horn if the other car starts to cut you off.
