The Garo language primarily uses which script?

The correct answer is: d) A unique Garo script.

The Garo language is spoken by the Garo people, who are indigenous to the Garo Hills region of Meghalaya, India, and Bangladesh. The Garo language has its own unique script, which is not related to any other script in the world. The Garo script is written from left to right, and each letter represents a single sound. The Garo script is used for both writing and printing.

The other options are incorrect because:

• Bengali script is used for writing the Bengali language.
• Roman script is used for writing many languages around the world, including English, Spanish, and French.
• Devanagari script is used for writing the Hindi language.
