Assertion: Jewellery has been found in the burials of both men and women.

Reasoning: On the whole, the Harappans firmly believed in burying precious things with the dead.

The Assertion is correct but the Reason is incorrect.

Burial Practices in Harappan Civilisation:

The Harappans used different kinds of methods to bury the dead like Complete burial, Fractional burials, and Cremation followed by burial of the ashes.
The dead bodies were generally placed in a north-south direction and were generally accompanied by various objects which were generally not as expensive as those found in the Egyptian and Mesopotamian civilizations.
Burials in Harappan sites typically involved laying the dead in pits, with some variations in the way the burial pits were made, such as lining them with bricks.
The significance of these variations in burial pits as indicators of social differences is uncertain.
Some graves in Harappan sites contain pottery and ornaments, suggesting a belief in their use in the afterlife.
Jewellery has been found in the burials of both men and women, indicating its importance in Harappan funerary practices.
An excavation in Harappa revealed the discovery of an ornament near the skull of a male, consisting of three shell rings, a jasper bead, and hundreds of microbeads.
Some instances show that the dead were buried with copper mirrors, although it seems that the Harappans, in general, did not believe in burying precious items with the deceased.
