In terms of the Central Civil Services (CCS) Rules and Fundamental Rule 17, the period of 'dies non' (a day which does not count for service benefits like increment, pension, or leave) is applied in the following specific circumstances:

• Statement 1 is correct: When an official remains absent from duty without prior information or authorized leave.
• Statement 2 is correct: When an official, though present in the office, leaves the premises without proper permission during working hours.
• Statement 3 is correct: When an official is present in the office but refuses to perform the duties assigned to them (often during strikes or 'pen-down' protests).

Statement 4 is incorrect: Late attendance is usually managed by debiting half-a-day’s Casual Leave (CL) for every three days of late coming. It is not marked as dies non unless it involves a total unauthorized absence or a specific disciplinary order. Therefore, the correct code is 1, 2, and 3.
