I practiced a question similar to this, and I believe the router ID defaults to the highest IP address on an active interface. So, I lean towards option B too.
I think if there's no loopback or configured router ID, OSPF will just pick the highest IP address from the up/up interfaces. That sounds like option B.
This looks like a straightforward question about accessing data from an accelerometer object. I'll carefully review the code options and think through which one would retrieve a single update.
Haha, I bet the person who wrote this question was trying to trip us up. Choosing the lowest IP address and incrementing it by 1? That's just too random to be true.

Aha! I remember learning about this. The correct answer is B - the highest up/up physical interface IP address is selected as the router ID. It's a good thing I reviewed that OSPF configuration section.
