A is correct. Although, B's AIC is slightly lower- you have to also consider the Adj R2 and the R2 value- R2 is closer to the Adj R2 and the adj R2 is lower. That extra variable in B can be slight overfitting of the model.

Option A has the Highest Adj RSq and the Lowest AIC. I think you are confused.
