Since the question wants the one false statement among four, the quickest approach is to check the option with the most specific number first, since exact figures are the easiest to verify against the statute.
Three statements hold up against the Act and one does not, which settles the question.
The correct answer, the statement that is not true, is Such interested persons may file objections within 6 months of the notice having been issued.
Section 15 of the Right to Fair Compensation and Transparency in Land Acquisition, Rehabilitation and Resettlement Act, 2013 fixes a strict sixty day window, running from the date of the preliminary notification, within which any person interested in the land may object to the acquisition. Keeping this figure in mind resolves the question quickly.
Measured against the actual sixty day rule in Section 15, only the six month claim fails to hold up.
The correct answer is Such interested persons may file objections within 6 months of the notice having been issued.
