Can any one of the business verticals, which are required to be registered under the Act, of a taxable person take registration as a person paying tax u/s 10

No. If any one business vertical of a taxable person becomes ineligible for paying tax u/s 10, then all other business verticals of the said taxable person shall become ineligible for paying tax u/s 10.
