Dear Aspirant,

EWS category is economically weaker section category which is eligible to the candidates whose family income is less than 8 lakhs per annum with some other conditions. EWS category is a sub category of General/Open category. All the candidates under EWS category are General/Open category candidates. So, if it is showing OC , means Open category there is nothing to worry about.

Hope I answered your query, thankyou!
