Probably B because if you use abbreviations you can type quicker but idk
I believe it is A due to "The lady made detailed plans, engaged the caterer and the orchestra well in advance" isn't exactly connect well and be hard to understand so you'd put a comma between "caterer, and".
Most people would probably say good because you would be filled with energy and youth forever but on the downside you'd also miss out on a lot of things adults get to do.
I would personally say bad because instead of being stuck in school or having to listen to your parents you could find your dream job, spend time with friends, travel, etc. You can't get a job as a child until you're 16 but you are still under your parents control. So I think that it would be bad.
How this helps! :)
The answer would be hearkens which means "to listen"
Hope this helps! :)
