Hi aspirant,

Yes one can definitely appear for NDA examination even he/she is from Arts background but they must have Mathematics as a subject. Also they would not be considered for Navy and Airforce wings which requires Physics and Chemistry as Subjects. He/She would need to fulfill other criteria as well such like age, educational qualification, physical standard, nationality etc. the details for which could be seen at NDA Eligibility Criteria 2022 - Age Limit, Qualification, Nationality, Attempt Limit (careers360.com)

Hope it helps!!
