Are you sure those are the only answer choices? Typically a chemical indicator is advantageous because results are almost immediate and very easy to read.  

I would say to rule out the second option simply because "limited use" doesn't sound like it would be an advantage.

I am thinking the answer is the first choice if you need to choose from that list. Requiring the use of electricity doesn't sound like an advantage either. Hope it helps!
