Explanation:

The idiom "cost an arm and a leg" means something is extremely expensive. The sentence says cell phones once cost an arm and a leg, and now most people can afford them. So the idiom suggests cell phones were once very expensive. The first option is wrong as the idiom isn't about trading, and the third is wrong as it's about high cost, not price variation.

Cell phones were once very expensive.
