Historical Writing Systems

The Indus script remains undeciphered despite numerous attempts by scholars. While some researchers propose connections to Dravidian or other languages, none have been conclusively proven. The script consists of pictographic symbols whose meaning and language affiliation remain unknown.

The term leet is derived from the word elite. The leet alphabet is a specialised form of symbolic writing. 

A pasigraphy is a writing system where each written symbol represents a concept.

Cuneiform script is one of the earliest systems of writing, distinguished by its wedge-shaped marks on clay tablets.

In 326 BC, Alexander (a Greek) invaded India. The Greek conquest unveiled India for the first time to the Western world and established contact between the people of both regions. The introduction of new scripts — Aramaic, Kharoshti and the alphabet style Yavanani by Panini— can be traced to Greek source.

Some of the inscriptions do carry dates as well.

Correct answwer is (3). 

Hindi is written in the Devanagari script, which is also used for several other Indian languages including Sanskrit, Marathi, and Nepali. Devanagari is an abugida (alphasyllabary) written from left to right and is characterized by the horizontal line running along the top of letters. Persian uses Arabic script, Roman is Latin script, and 'Sanskriti' is not a script but a word meaning culture.

The Chinese writing system is ideographic, where characters represent ideas or concepts rather than just sounds. Each character typically carries meaning and can stand alone as a word. This distinguishes Chinese from purely phonographic or alphabetic scripts where symbols primarily represent speech sounds. While early Chinese characters had pictographic origins, the modern system is fundamentally ideographic.

Kalidasa, the greatest poet and dramatist of Classical Sanskrit, composed all his works in Sanskrit. His famous works include Abhijnanasakuntalam, Meghaduta, and Raghuvamsa.

This is the correct option. Sanskrit was the language meant almost exclusively for the priests and elites.

This is the correct option. Aramaic and Greek scripts were used for inscriptions in Afghanistan.

The Brahmi script is the earliest known Indian writing system, dating back to the 3rd century BCE during the Mauryan period. It was used to write Ashokan edicts and is the ancestor of most modern Indian scripts. Mori is not a recognized script, Devanagari evolved later, and Kharosti was used in northwest India but not the earliest.
