So that's why when you ask for demat account, they suggest you to open three in one account that is bank+demat+trading account and link three accounts. I checked you have query related to brokerage part. You can clear you doubt by checking with brokerage plan you opted for.

Many banks like Kotak Mahindra bank, ICICI Bank, Punjab National Bank, and also companies dealing in Shares and Mutual funds trading like Motilal Oswal, Sharekhan, Religare Securities etc are dealing with Demat accounts.
