Solution

The correct option is A Gold is the most malleable metal
Malleability is a substance's ability to deform under pressure. A malleable material may be flattened into thin sheets by hammering or rolling it. Rutherford wanted the thinnest layer possible to get the accurate results of the alpha particle scattering experiment.
Therefore, gold was used in the experiment for best result.
