Compared with gas burners, induction burners generally offer which characteristic?

• A. They require an open flame
• B. Induction burners have no open flame
• C. They are less energy-efficient than gas
• D. They heat unevenly

Answer: (B)

Induction cooking heats by a magnetic field that induces current directly in the pan, so heat is generated in the cookware rather than on the surface. Because nothing is burning on the cooktop, there is no open flame. This design also tends to be more energy-efficient than gas since energy stays in the pan and little heat is lost to the surrounding air, and the heat can be adjusted quickly for precise control. The other options don’t fit: there isn’t an open flame with induction, it’s generally not less energy-efficient than gas, and while heating can vary with cookware, induction is not defined by inherently uneven heating.
