Nazariyan ornament is worn in which part of the body by women?

The correct answer is C. Neck.

Nazariyan is a type of necklace that is worn by women in the Indian subcontinent. It is made up of small, round beads that are strung together on a chain. The beads are usually made of glass, but they can also be made of other materials, such as gold or silver. Nazariyan are often decorated with intricate designs, and they are believed to protect the wearer from evil eye.

The other options are incorrect because they are not parts of the body where nazariyan are typically worn. Arm, foot, and ears are all parts of the body where other types of jewelry are often worn, but nazariyan are typically worn around the neck.
