The correct answer is: c) Post-Independence era.
The Meetei Mayek (Meitei Mayek) script is the native writing system of the Meitei people of Manipur, India. It is a phonetic script that is written from left to right. The Meetei Mayek script was first developed in the 13th century, and it was used extensively until the 19th century. However, in the 19th century, the British colonial government introduced the Bengali script to Manipur, and the Meetei Mayek script fell into disuse.
In the post-Independence era, there was a renewed interest in the Meetei Mayek script. This was due to a number of factors, including the rise of Meitei nationalism, the desire to preserve Meitei culture, and the recognition of the Meetei Mayek script as a UNESCO World Heritage Site. As a result of this renewed interest, the Meetei Mayek script is now being used more widely, and it is being taught in schools in Manipur.
The other options are incorrect because:
- The 19th century was a time when the Meetei Mayek script fell into disuse.
- The early 20th century was a time when the Meetei Mayek script was still in disuse.
- The 1990s was a time when the Meetei Mayek script was beginning to be revived, but it was not until the post-Independence era that the Meetei Mayek script was revived in earnest.
