The correct answer is Balakot. Key Points - Balakot is one of four known ancient coastal sites in Pakistan. - These sites remained unexcavated until the opportunity arose in 1973 to launch a project at Balakot. - Fishbones and shells dominate the faunal remains. - People engaged in the manufacturing of jewelry, especially bangles and perhaps inlays for wooden furniture, from shells. Hence it was a specialised centre for making shell objects.
