Select the most appropriate option to substitute the highlighted segment in the given sentence.
Elastocaloric cooling is a promising, eco-friendly technology for refrigeration that has the potential to be used by a broad range of applications and at different temperature ranges.

Correct option is B

✔️ Correct option: (b) potential to be used in
Correct sentence: “...has the potential to be used in a broad range of applications and at different temperature ranges.”
Explanation:
The phrase "used in" is appropriate when referring to application within a field, method, or process. “Used by” would incorrectly imply agency or user, not applicability.
Grammatical rule used:
The preposition “in” is used to describe where something is applied, whereas “by” is used to show who is using it.
✦ Hindi explanation: “Use in” का प्रयोग तब होता है जब कोई वस्तु या तकनीक किसी क्षेत्र में प्रयोग होती है, जैसे – “used in medicine.”
