wild guess par 2 ya 4 hai kya?

yep

Is it (2)??

so i am thinking about the ligand interactions with metal ion
ab Ca(OH)2 to hona hi best hai ye to obvs hai
phir ag aur pb raha main
ab i think pb ke sath better hona
to 4?

uhh, it has some inorganic mixed in this question
we know Ca(OH)2 is a sparingly soluble salt and rest are insoluble salts
so, the solubility of Ca(OH)2 will be higher than the other three [also can be judged by AB2 and AB salt expression of solubility, where it is 4s^3 for AB2 and s^2 for AB salt]
ab, we have learnt in inorganic that HgS has very low Ksp, so it comes in the end
now, to distinguish between AgBr and PbS ki Ksp, our sir taught a "fitrat/habit" trick, i.e. in general koi ion kya habit/fitrat dikhata hai jab vo koi salt banata hai
we know all chloride, bromide, iodide salts are water soluble except Ag+, Hg+, Pb+2, Cu+ & HgI2 and BiI3
also, all sulphide salts are water insoluble except s-block
to hamare sir ne bataya ki halide ions ki fitrat hai ki vo solube salts banaye kuch compounds ko chodhkar aur sulphide ions ki fitrat hai ki vo insolube salts banaye sivaaye s-block
matlab halide ions sulphide ions se zyada solube hai in general aur unki Ksp S2- se zyada honi chahiye
isliye, iss question mei AgBr ki Ksp PbS se zyada hogi
and hence, I think it will be (2)
also, tbh it is a really good question, first thought was they haven't given solubility (s) of each so it is a incomplete question but then I thought of salt analysis chapter

isko Ksp ke alwa koi aur tarike se soch sakte hai?

Our sir taught the trick in salt analysis chapter only when we were discussing precipitation reactions
