I thought it could be wider, like -5 to 5?

Yup, definitely B! Classic geometric series rule.

Wait, how can it only be between -1 and 1?

The series converges for -1 < x < 1.

I thought the convergence criteria were broader than just -1 to 1. Maybe it’s option C or D? I need to double-check my notes.

I’m not entirely sure, but I feel like we did a similar question where the convergence was linked to the ratio being between -1 and 1. Could it be option B?

I remember something about geometric series converging when the absolute value of the ratio is less than 1. So, I think it might be -1 < x < 1.

I definitely recall that for geometric series, the common ratio must be less than 1 in absolute value. So, I’m leaning towards option B as the correct answer.

This looks like a tricky networking question. I'll need to carefully consider the requirements and think through the pros and cons of each option.

Hmm, the key here is being able to enable and disable monitoring for each level as needed. I think option B might be the best approach to achieve that flexibility.
