Hi Aspirant!

OBC - Other backward category , this term is used by the government of India to classify castes which are educationally or socially unprivilaged. And under this, two categories fall: Creamy layer and Non Creamy Layer (NCL). Creamy layer is for the wealthier and better educated members of OBC caste. And these people are not eligible for any benefit schemes/programs by Government. For creamy layer the annual family incme should be less than 6 lakhs.
