b i and iii only
c ii and iii only
d i, ii, and iii

Explanation:

To recommend a restaurant for the group using DineOutHelper, the app needs to know each group member's food allergies or dietary restrictions (as it has to accommodate all group members' allergies and dietary restrictions) and also the usernames of people on Brandon and Cynthia's contact lists (since Alejandra, who is organizing the meal, selects restaurants based on the contact list). Geographic location (II) is not relevant as the selection is based on contact - list restaurants (nearby restaurants based on contact list, not on geographic location in general).

Answer:

B. I and III only
