Ответ:
Electric hot plate
Explanation:
Considering that the liquid sample is flammable, it wouldn’t be a good idea to have it near a source of fire which the Bunsen burner provides, rather it would be better to heat through an electric hot plate as its not near a source of flame and instead produces heat through electricity.
