B. Producing hook-and-loop tape is not an example of research in the field of energy.
“A. developing rechargeable batteries” is research involving <em>electrical</em> energy.
“C. Determining the usefulness of oil from soybean plants” is incorrect. Soybean oil might be used as a fuel to provide <em>heat</em> (energy)
“D. studying the effects of insulation” involves retaining the <em>heat</em> (energy) inside a structure.

Answer:
5.95 L
Explanation:
V1/V2 = T1/T2
4.82 L/V2 = 243.1K/300.1K
V2 = 4.82*300.1/243.1 L = 5.95 L
