    option c is incorrect

    eduncle-logo-app

    any doubt then ask

    eduncle-logo-app

    isn't D the correct option?

    eduncle-logo-app

    only 0 and 2 are limit point

    eduncle-logo-app

    Range set doesn't have limit point since range set is finite , just sequence has limit point. Please correct me if I'm wrong.

    eduncle-logo-app

    in range set , there are only two elements which are occuring infinite times , so 0 and 2 is limit point

    eduncle-logo-app

    yeah , range set is finite...but occuring infinite times

    eduncle-logo-app

    Yeah , Occuring infinite times it implies sequence has limit points not range set

    eduncle-logo-app

    yeah , understood
