Which of the following provisions of the Trade Marks Act, 1999 shall apply to certification Trade…

The certification-mark provision expressly excludes the nondistinctiveness and customary-use clauses from the listed set. It does not exclude the listed descriptive-character or deception provisions, so those two provisions form the complete applicable set.

Why not "A and C only"? This combination selects precisely the two listed clauses that the certification-mark provision expressly makes inapplicable. It therefore reverses the statutory exclusion and also omits the descriptive-character and deception provisions, which remain applicable among the choices presented in the question's fixed list.

Why not "A and D only"? The deception provision remains applicable, but the nondistinctiveness clause paired with it is expressly excluded for certification marks. This combination also omits the listed descriptive-character provision, so it contains an inapplicable clause and fails to include the complete set of applicable clauses.

Why not "All four listed provisions: a), b), c) and d)."? Applying every listed provision disregards the express statutory exclusion of the nondistinctiveness and customary-use clauses for certification marks. Only the listed descriptive-character and deception provisions remain applicable, so adding the excluded clauses makes this aggregate alternative legally broader than the Act allows.
