The correct answer is B. Bronze is an alloy consisting primarily of copper, commonly with about 12–12.5% tin and often with the addition of other metals (including aluminium, manganese, nickel, or zinc) and sometimes non-metals, such as phosphorus, or metalloids such as arsenic or silicon. These additions produce a range of alloys that may be harder than copper alone, or have other useful properties, such as strength, ductility, or machinability.
A is incorrect because bronze is not a mixture of copper and magnesium. Magnesium is a light metal that is not typically used in bronze alloys.
C is incorrect because bronze is not a mixture of copper and zinc. Zinc is a metal that is typically used in brass alloys, not bronze alloys.
D is incorrect because bronze is not a mixture of copper and lead. Lead is a heavy metal that is not typically used in bronze alloys.
