|Gun metals is also called as red brass and the composition present in it are copper 88% tin 10% and zinc 2%. Among the given option cu and sn are matched.
So option D is correct.

|Gunmetal, also known as red brass in the United States,
 is a type of bronze " an alloy of copper (88%), tin (10%), and zinc (2%).
 Originally used chiefly for making guns, gunmetal was eventually superseded by steel. Gunmetal casts and machines well and is resistant to corrosion from steam and salt water,
 and is used to make steam and hydraulic castings, valves, and gears, and also statues and various small objects, e.g. buttons. It has a tensile strength of 221 to 310 MPa, a specific gravity of 8.7, a density 8,719 kg/m3, and a Brinell hardness of 65 to 74.

|Gunmetal contains 86% copper, 9.5% tin.|
|Vaishnavi said: (Dec 26, 2018)|
|It is an alloy of copper, tin, and zinc. Proportions vary by approximation but 88% copper, 8"10% tin, and 2-4% zinc is an approximation.|
|Rajendra Roul said: (Jul 18, 2019)|
|Gun metal is an alloy of 10%cu + 1%sn + 1%zn + 88%pb.|
