Hey aspirant

As the question says, you need to select the type of the institution in which you studied and then appeared for the qualifying examination. The options are private, Government, Kendriya Vidyalaya Sangathan or Jawahar Navodaya Vidyalaya.

Since your institution has been private, so select the private option and then proceed.

Hope this helps

Hii!
You haven't specified whether you are asking for ICAR UG or PG entrance examination. However, you need to select the option, from where you completed your last degree or qualification. So, if it's a private school or private college, choose private as an option.
Hope this helps.
Good luck!
