Gold

Explanation:

We have

where, $Q$ is heat supplied, $m$ is mass, $C$ is specific heat capacity and $\Delta T$ is rise in temperature.

Thus, higher the $C$, greater is the heat required to hear it to a certain temperature.

Gold has the least Specific Heat capacity among the options, hence will require the least amount of heat to raise the temperature.

the old alchemists made significant contributions to science even though there starting premises were off a bit. their conclusions after failure would steer them into better directions for investigation. science is no more than close observation and the initial mistakes result in rethinking and retrying experiments.
