Archaeologists have classified some of the artefacts discovered from the Harappan site as luxuries if these were rare or made from costly, non-local materials or with complicated technologies. 'Faience' was a luxurious material used to make:
1. Precious ornaments
2. Religious sculpture
3. Little pots
4. Unique agricultural tools

The correct answer is Option 3 - 3 (Little pots)

NCERT: Miniature pots of faience, perhaps used as perfume bottles, are found mostly in Mohenjodaro and Harappa, and there are none from small settlements like Kalibangan......Another strategy to identify social differences is to study artefacts, which archaeologists broadly classify as utilitarian and luxuries. The first category includes objects of daily use made fairly easily out of ordinary materials such as stone or clay. These include querns, pottery, needles, flesh-rubbers (body scrubbers), etc., and are usually found distributed throughout settlements. Archaeologists assume objects were luxuries if they are rare or made from costly, non-local materials or with complicated technologies. Thus, little pots of faience (a material made of ground sand or silica mixed with colour and a gum and then fired) were probably considered precious because they were difficult to make."
