A
15 days
B
21 days
C
26 days
D
30 days
Correct answer: (b) 21 days
Explanation
- A
15 days
Fifteen days is not the statutory window under the Registration of Births and Deaths Act as applied in CRS teaching. The mandated period is 21 days.
- B
21 days
Under the Civil Registration System, birth and death must be registered within 21 days of the event (Registration of Births and Deaths Act, 1969). That is the official key.
- C
26 days
Twenty-six days is not the legal period.
- D
30 days
Thirty days is a common guess (and some delayed-registration slabs use other intervals) but the basic mandatory window taught here is 21 days.
Summary. Official key is (b) 21 days. CRS/RBD Act requires registration of birth and death within 21 days. 15, 26 and 30 are distractors.
