Step 1: Structure of the Lok Sabha.
The Lok Sabha is the lower house of the Parliament of India. Members of the Lok Sabha are directly elected by the people of India through general elections.
Step 2: Evaluation of statement P.
Statement P says that the Lok Sabha has no nominated members. After the 104th Constitutional Amendment (2020), the provision for nomination of Anglo-Indian members was removed. Therefore, the Lok Sabha currently has no nominated members.
Step 3: Evaluation of statement Q.
The normal term of the Lok Sabha is five years. However, during a national emergency, Parliament may extend the term of the Lok Sabha by one year at a time. Therefore, this statement is correct.
Step 4: Evaluation of statements R and S.
Statement R is incorrect because the President no longer nominates members to the Lok Sabha. Statement S is also incorrect because the Lok Sabha can only be dissolved by the President, not the Speaker.
Step 5: Conclusion.
Therefore, the correct statements about the Lok Sabha are P and Q.
Final Answer: P and Q.
