Which script is used to write 'Hindi'?

Devanagari

The correct answer is Option (2) → Devanagari

Most scripts used to write modern Indian languages are derived from Brahmi, the script used in most Asokan inscriptions. From the late eighteenth century, European scholars aided by Indian pandits worked backwards from contemporary Bengali and Devanagari (the script used to write Hindi) manuscripts, comparing their letters with older specimens.
