C - sat in the back
They didn’t ask for the sentence right?
If they didn’t ask, then it’s still C.
I would say that the best summary of this paragraph is C) Systems transmitting information across a distance are called telegraphs. The word telegraph originates from Greek words.

I'm pretty sure its B. I am not 100% positive, but it sounds correct to me. Please let me know if I am correct or not and I really hope this helps.
