Solution

The correct option is A
Ag, Cu and Pb

All ores are minerals but not all minerals are ores.
For a mineral to be an ore, it should be profitable to extract the metal from the ore.

Argentite is $A g_{2} S$ - an important ore of silver.
Likewise, galena - $P b S$ , is an important ore for lead.
Copper has several sulphide ores including $C u_{2} S$ , $C u S$ and \(CuFeS_2)\.
