The correct answer is B. Lead and antimony.
Type metal is an alloy of lead and antimony, with small amounts of other metals such as tin and copper. It is used in printing presses to create type, which is the raised letters that are used to print text. Type metal is a hard and durable alloy that can withstand the wear and tear of printing presses. It is also a good conductor of heat, which helps to ensure that the type is evenly inked.
Lead is a soft, malleable metal that is easily melted and cast. It is also a good conductor of heat and electricity. Antimony is a hard, brittle metal that is used to harden lead. It also helps to improve the machinability of lead. Tin is a soft, white metal that is used to improve the fluidity of lead and to make it easier to cast. Copper is a red metal that is used to improve the strength and durability of lead.
The other options are incorrect. Option A is incorrect because copper is not a major component of type metal. Option C is incorrect because bismuth is not a major component of type metal. Option D is incorrect because zinc is not a major component of type metal.
