Correct answer: (b) 60 days
Explanation
- A
30 days
Thirty days is shorter than the constitutional period. Absence for a month without permission does not by itself trigger the vacancy rule. This option is not the key.
- B
60 days
Article 101(4) says that if a member of either House is absent without permission for a period of sixty days, the House may declare the seat vacant. That sixty-day rule is the official key.
- C
90 days
Ninety days is used in other constitutional clocks, such as some President’s-rule related counts, not this disqualification-by-absence rule. This option is therefore wrong.
- D
120 days
One hundred twenty days is not the Article 101(4) period. This option is not the key.
Summary. Official key is (b) 60 days. The Constitution lets a House declare a seat vacant after sixty days of unpermitted absence, not automatically at thirty, ninety or one hundred twenty. The House may still grant leave. Only (b) is the stated period.
