Detailed Solution

Concept- Sweets are frequently covered in foil in the colour of silver. The name of this foil is "vark" or "varak." It is a very thin sheet of pure metal foil, usually made of silver and gold.
Silver can be hammered into incredibly thin sheets that are only a few micrometres thick since it is a malleable metal.
Because silver foil does not react with other metals, it is safe to eat and is used as a garnish for desserts because eating it won't result in any dangerous side effects.
Although the other metals listed in the alternatives are likewise malleable and can be hammered into extremely thin sheets known as a foil, they may not always be suitable for human consumption. Copper foils can be used for many different things, including colouring glass. The tape made of copper foil is frequently used in electronics and motors.
Aluminium foil is frequently used to wrap and store food, as well as to protect baking surfaces from moisture loss while baking. Aluminium is not used to decorate or garnish sweets or other goods, despite the fact that metal is not always detrimental to our bodies.
From the explanation above, it is clear that silver foils are used to decorate sweets.
Hence, the correct answer is option 3.
