1. I guess so, though "show" does not seem the best choice of verb.
2. Yes. If I had to guess, I would guess that B is the expected answer.
3. B is the better answer.
4. Yes.

This sentence?

4- The fire grew quickly because it hadn't rained for many years.

Sentences are not modifiers.

There is one dependent clause: "because it hadn't rained for many years."

It is not a modifier, but an optional adjunct.

There is a subject - it, and a verb had rained.

Is this what you referred to as dangling modifier ? it hadn't rained......for many years.

For many years - is a preposition phrase acting as an adverbial modifier for "hadn't rained." which is grammatical.

Look at this sentence in another angle. even though many experts are against starting a sentence with "because", it can be rewritten as " Because it hadn't rained for many years, the fire spread quickly". Some people think it is fine as long as there is a reason and a result in the context to adjustify the use.
