Section 167(2) of the CrPC creates default bail once investigation runs past a fixed period without a charge sheet being filed. The question asks what that period is, and each option needs to be measured against the actual statutory scheme.
Only the sixty or ninety day scheme, keyed to the severity of the offence, reflects how Section 167(2) actually operates.
Therefore, the correct answer is After 60 days or 90 days, contingent upon the maximum punishment prescribed for the offence.
