Read the passage and answer the questions:

Mesopotamian texts datable to the third millennium BCE refer to copper coming from a region called Magan. Interestingly enough copper found at Mesopotamian sites also contains traces of nickel. Other archaeological finds suggestive of long-distance contacts include Harappan seals, weights, dice and beads. Mesopotamian texts mention contact with regions named Dilmum. Magan and Meluhha. They mention the products from Meluhha: Carnelian, lapis lazuli, copper, gold, and varieties of wood. A Mesopotamian myth says of Meluhha: "May your bird be the haja-bird, may its call be heard in the royal palace."

Specialised drills have been found at which of the following Harappan sites?

A. Nageshwar
B. Dholavira
C. Lothal
D. Balakot
E. Chanhudaro

Choose the correct answer from the options given below:

B, C, E only

The correct answer is Option (2) → B, C, E only

A. Nageshwar
B. Dholavira
C. Lothal
D. Balakot
E. Chanhudaro

Archaeologists’ experiments have revealed that the red colour of carnelian was obtained by firing the yellowish raw material and beads at various stages of production. Nodules were chipped into rough shapes, and then finely flaked into the final form. Grinding, polishing and drilling completed the process. Specialised drills have been found at Chanhudaro, Lothal and more recently at Dholavira.
