Hello

I am guessing that it's about upsc civil services examination.

Yes, you can definitely write your GS paper answers in English even if you have chosen Hindi literature as your optional paper, being a language subject you will have to write your Hindi literature optional paper answers in Hindi .

This is because,

The UPSC Prelims and Mains examination question paper are set in both English and Hindi except the language papers -A and B in mains examination while prelims examination is objective, Mains examination is subjective and you have the option to write your  answers in English  or in any one of the Eighth Schedule languages .

So, beside English , you have the option to write answers in the language included

in the Eighth Schedule to the Constitution which consists of  22 languages  listed below:-

-) Assamese

-) Bengali

-) Gujarati

-) Hindi

-) Kannada

-) Kashmiri

-) Konkani

-) Malayalam

-) Manipuri

-) Marathi

-) Nepali

-) Odia

-) Punjabi

-) Sanskrit

-) Sindhi

-) Tamil

-) Telugu

-) Urdu

-) Bodo

-) Dogri

-) Maithili

-) Santhali

To help you for further, here's a brief of UPSC examination pattern

UPSC civil services examination  has 3 stages listed below :-

*prelims exam :- it is objective paper and is of qualifying nature , so you just  need to at least qualify it to be eligible for mains examination, the score /marks obtained by you in your prelims examination is not added up or used in your final merit. Your prelims exam consist of 2 papers: -

The compulsory indian language and english are qualifying in nature . You just need to qualify them. The marks obtained by you in these two papers will not be counted towards merit list.
