Assuming that you could fly whenever you wanted to, I would choose Option B. I would not worry about getting experience with radio comms and busy airspace. For the initial part of your training that is the last thing you want. Later on it is easy to build up experience by flying to the busier airports with your instructor.
Option A might be better if aircraft/instructor availability is not an issue. It is quite useful to live close to your school as you will be more likely to take a chance with the weather.
