Trouble identifying my 2.3 L Quad Four motor

[zakk74]

I was trying to sign up for auto zones free car manual and one question is which 2.3 motor it is thats in my particular car. How do I find this information? The choices were between 2.3 L 3,a,or d. its a question of whether its single or dual overhead cam, and the a class is a high output motor which i dont think it is since the autozone page says only 1% of the achievas got that motor that year
