As we have learnt, 

Both \text{Pb}^{2+} \text{ and } \text{Ag}^{+} belong to Group 1 of basic radicals and form white precipitates of their respective chlorides.

But \mathrm{PbCl}_{2} is soluble in hot water while \mathrm{AgCl} does not dissolve in hot water.

So, hot and dilute \mathrm{HCl} will be able to distinguish between the given ions.

Hence, the correct answer is Option (2)
