When you see a green arrow pointing right, it indicates that you have the right of way to make a right turn. This signal means that the intersection is clear for you to proceed without stopping, provided that the roadway is unobstructed. Consequently, turning right is the required action at that moment, making this option the most precise response to the question.

Other actions, such as checking for pedestrians, while always a good practice, are not specifically mandated by the green arrow. You are expected to be aware of your surroundings, but the presence of the green arrow primarily signals that you can turn safely. Stopping is not appropriate in this scenario unless there are pedestrians or other unforeseen hazards, and there is no instruction to go straight since the specific indication is to turn right.
