Right choice is (b) False

Easy explanation: For properties of copper to be used, but with more strength, this copper needs to be mixed with certain material, which will provide it the required strength. Cadmium, silver and aluminium oxide are few of those materials which will aid in increasing its strength. This process of increasing strength is done by treating the alloy through cold working.
