How many members in Lok Sabha are nominated and not elected?

The Constitution allows the President to add members to the Lok Sabha who are not chosen through direct election, to represent a community that may otherwise lack adequate representation. Under Article 331 (as it originally stood), this nomination power applied specifically to the Anglo-Indian community: the President could nominate not more than two persons from that community if it was not adequately represented in the House.

This question is from the CTET December 2019, Paper 2 exam, held on 8 December 2019. On that date, Article 331 was still in force -- the provision for nominating Anglo-Indian members was abolished only later, by the Constitution (104th Amendment) Act, 2019, which took effect from 25 January 2020. So, as on the exam date, the President could still nominate up to two Anglo-Indian members to the Lok Sabha, and the official CBSE answer key for this question confirms this count.

• "4 (four)" maps to no Lok Sabha nomination provision; the closest analogous power, the Rajya Sabha's Article 80 nominee provision, sets a ceiling of twelve for a different category of persons in a different House.

• "1 (one)" is the ceiling Article 333 sets for nominating an Anglo-Indian member to a State Legislative Assembly -- a separate provision from Article 331, which governs the Lok Sabha.

• "0 (none)" describes the position only after 25 January 2020, once the 104th Amendment took effect -- it does not apply to this exam, which was conducted before that change.

So, for this pre-104th-Amendment question, the number of members nominated (and not elected) to the Lok Sabha is two.
