4. Mahavir plays a game on the number line. He starts at zero. At each second, he either stays where he is, or jumps some distance left or right. The distance he can jump at second s is 3s units (he does not have to jump every second, but when he does, he jumps exactly 3s units left or right). His time starts at s = 0. His goal is to reach the point 2023. He has devised a path to do the same in the minimum amount of time. How many times will he jump left on this path?
(a) 1
(b) 2
(c) 3
(d) 4
