Which of the following Harappan sites were located near the coast?

Nageshwar and Balakot

The correct answer is Option (2) → Nageshwar and Balakot

Nageshwar and Balakot, both located near the coast, were specialized centers for producing shell objects such as bangles, ladles, and inlays, which were then transported to other settlements. Similarly, finished products, including beads, from Chanhudaro and Lothal were likely taken to larger urban centers such as Mohenjodaro and Harappa.
