Best answer
Correct choice is (d) Statues

The explanation is: Admiralty gun metals have high corrosion resistance and casting properties. They are used for making pumps, valves, statuary and other castings. They contain 88% Cu, 10% Sn, 2% Zn, and 2% Ni. Leaded gunmetal is used for making bearings, marine castings, hydraulic valves etc.
