Explanation:

To understand the answer, let's break down the given options and analyze them one by one.

I) Silver:
Silver is a precious metal that has been used to make coins for centuries. It is known for its lustrous appearance and durability, making it an ideal material for coins. Silver coins are often marked or punched with various designs and inscriptions to identify their value and origin.

III) Copper:
Copper is another metal commonly used in coin production. It is known for its reddish-brown color and excellent conductivity. Like silver coins, copper coins are also punched or marked with various designs and inscriptions.

IV) Bronze:
Bronze is an alloy made primarily of copper and tin. It is often used in the production of coins due to its durability and resistance to corrosion. Bronze coins, like copper coins, are punched or marked with different designs and inscriptions.

Now let's consider the options:

a) I and IV: This option includes silver and bronze coins. While bronze coins are punched or marked, silver coins are not made of bronze. Therefore, option a) is incorrect.

b) III and II: This option includes copper and gold coins. While copper coins are punched or marked, gold coins are not typically punched or marked. Therefore, option b) is incorrect.

c) I and III: This option includes silver and copper coins, both of which are commonly punched or marked. Therefore, option c) is correct.

d) II and IV: This option includes gold and bronze coins. As mentioned earlier, gold coins are not punched or marked, and bronze coins are punched or marked. Therefore, option d) is incorrect.

In conclusion, the correct answer is option c) I and III, which means that silver and copper coins are punched or marked onto the metal.
