Which model listed has four cabin doors?

Explanation:
Emergency exit capacity drives door layout. The 737-700 is the smaller member of the group and is typically configured with two main entry doors on each side (one forward, one aft), giving four cabin doors in total. The longer 737-800 and 737-900 add more exit points to meet safety requirements for more passengers, and the B787, being a widebody, uses even more exits overall. So four cabin doors identifies the 737-700 as the model with that specific door count.
