Step 1: Understanding the Concept:
Chanhudaro was a small Harappan settlement located in present-day Pakistan, covering less than 7 hectares.
Step 2: Detailed Explanation:
Despite its small size, Chanhudaro was a major industrial hub of the Indus Valley Civilization.
Archaeologists have identified it as a center almost exclusively devoted to craft production.
The range of crafts included bead-making (using carnelian, jasper, crystal, and steatite), shell-cutting, metal-working, seal-making, and the manufacture of weights.
The discovery of specialized drills at Chanhudaro, Lothal, and Dholavira confirms the sophistication of their craft techniques.
Large quantities of waste materials found at the site indicate that it functioned as a workshop for producing finished goods for larger urban centers like Mohenjodaro.
Step 3: Final Answer:
The primary focus of Chanhudaro was craft production. Thus, option (d) is correct.
