Section 23 Trade Marks Act 1999 deals with REGISTRATION of accepted trade marks. After acceptance and absence of opposition (or successful resistance), the Registrar shall:

1. Section 23(1) Trade Marks Act 1999: 'Subject to the provisions of section 19, when an application for registration of a trade mark has been accepted and either — (a) the application has not been opposed and the time for notice of opposition has expired; OR (b) the application has been opposed and the opposition has been decided in favour of the applicant, the Registrar shall, unless the Central Government otherwise directs, register the said trade mark and the trade mark when registered shall be registered as of the date of the making of the said application and that date shall, subject to the provisions of section 154, be deemed to be the date of registration.' 2. Section 23(2): on registration, the Registrar issues a certificate. 3. Hence option B is correct. _Source: Patents Act 1970 / Copyright Act 1957 / Trade Marks Act 1999 — Trade Marks Act 1999, Section 23_
