Mobile Suica question, buying a monthly commuter pass

So, the android version of mobile Suica is only in Japanese, fair enough, my Japanese not being the greatest, I have a question about which option to choose.

There are 3 options

1.通勤/オフピーク (時差通勤) 定期券
Commuting/off-peak (staggered commuting) commuter pass

2.グリーン定期券
green commuter pass

3.通学定期券School commuter pass

Now obviously I’m not a student and I want to be able to use the train at any time of the day, but I certainly don’t need green class cars. Is this just a way os saying regular commuter pass? Is option 2 the correct choice?

Thanks in advance!
