B seems like the most logical choice. Transient noise is a short-lived power line disruption.

Haha, C is definitely not the right answer. Prolonged power supply below normal voltage? That's just called a brownout!

I vaguely recall that transient noise is about brief disturbances, so B seems like the most plausible answer to me.

I feel like we had a practice question that mentioned fluctuations, which makes me think D is definitely not correct.

I remember studying about voltage conditions, but I'm not sure if A is really what transient noise refers to.

I'm pretty confident the answer is B. Transient noise is a brief power disruption, not a long-term voltage issue.

Wait, is transient noise the same as a power surge? I'm a bit confused on the difference between those terms.

Okay, I've got this. Transient noise is a short-term voltage drop, so the answer is B. Short duration power line disruption.

I'm not totally sure about this one. I'll have to think it through carefully and eliminate the options that don't seem right.

Hmm, I think it's either A or B. Transient noise sounds like a temporary power issue, not a prolonged one.
