For MHT CET counselling, you should claim the OBC (Other Backward Class) category during the application process. The specific sub-category (3B) might not be directly applicable.

MHT CET counselling typically follows the reservation system set by the Government of Maharashtra. This system categorizes candidates into Open (General), OBC, SC (Scheduled Caste), ST (Scheduled Tribe), VJ/DT (Vimukta Jati and Denotified Tribes), NT (Nomadic Tribe), EWS (Economically Weaker Section), and PwD (Persons with Disabilities).

While there might be sub-categories within OBC (like 3B, which you mentioned), the MHT CET counselling process might simply consider you under the broader OBC category.
