I could but the problem with that is I don't understand the most spoken Language of our country the reason you may know which is I am from the southern most region. It should be someone who can understand Hindi primarily even though if they are not familiar with the regional languages.
I don't see how that can be a reason for you (or anyone else for that matter) to not apply for a merit source status since you use English language only in your local board. Or something changed there and now you use other languages as well?
English language is predominantly used in the main board of Indian LB but Hindi language speakers probably over 80% of total Indian population that's why it's important that someone who is going to represent the Indian board should be familiar with the most spoken language.
