Answer:
The photojournalist might be the best career option.
Step-by-step explanation:
Firstly, being a print journalist would just be being a normal journalist, meaning they might have to work with a camera crew, other journalists and just people in general. Although the number of people is small, it is not the best option here. Also, being a journalist typically means just reporting and interviewing, and there are not many aspects of technicality or production there.
Secondly, being a camera operator almost certainly puts you in with a camera crew, which does not suit the person in the question due to them not liking working with a large number of people. Although there is a lot of technicality in this career choice, it is not the best.
Finally, being a videographer means going to live events, weddings and even documentaries to film. Again, that would entail working with quite some people, like the hosts at the live events or weddings, say, and there is not a lot of technicality in there.
Being a photojournalist, however, would mean often going out solo to capture pictures or video of the event you want to report, going back to the studio or your own home to piece and report the event, and publish it. Not much contact with other people, and a lot of technicality like editing and publishing.
Therefore, the photojournalist might be the best career option.
Hope this helped!
