Communication, collaboration, and crowdsourcing

Khan Academy offers an online coding environment for writing programs and webpages. We've considered adding a pair programming mode to the environment, so that two Khan Academy users can collaborate on a program simultaneously.

Which of these is a benefit of a pair programming mode?

(Choice A)
Khan Academy will not have to store any of the code they type into the program, since each of the user's computers can store it.
(Choice B)
A user that is nervous about writing incorrect code doesn't need to worry about other users seeing their code in an incorrect state.
(Choice C)
Users can feel more secure knowing that no cyber criminals can see what they're programming.
(Choice D)
Users can create a single shared program with contributions from both of them, and iterate on it quickly.
