Who among the following has deciphered the script of Harappan people?

The script has not been deciphered yet

The correct answer is Option (4) - The script has not been deciphered yet

While there have been attempts to decipher the Harappan script, also known as the Indus script, none have been universally accepted by the scientific community. Some prominent figures like John Marshall, Alexander Cunningham, and James Prinsep made significant contributions to the study of the Indus Valley Civilization, but they were not involved in deciphering the script.

Asko Parpola is a leading expert who has dedicated decades to understanding the Indus script. He has proposed a decipherment based on the Dravidian language family, but his work is still under debate.

The lack of bilingual texts and a limited understanding of the Harappan language make deciphering the script a complex challenge.
