Which among the following States has the highest number of seats in the Lok…

Concept — Article 81 of the Constitution allots seats in the Lok Sabha to each State in proportion to its population, so that the ratio between a State's population and the number of seats given to it is, as far as practicable, the same for every State. The population used for this allotment is not the present-day one: it was frozen at the 1971 Census figures by the 42nd Amendment and kept frozen by the 84th Amendment until the first census taken after 2026. A State's seat count therefore reflects its 1971 population share and does not rise as its population grows.

Application — Read off the fixed Article 81 allotment for each of the four States named in the question:

The largest of these four allotments is 48, so Maharashtra sends the most members to the Lok Sabha among the States named here.

Cross-check — Ordering the four allotments gives 48 > 42 > 39 > 25, which follows the order of these States by 1971 Census population, so the rule and the figures agree. Across the whole country Uttar Pradesh has the largest allotment at 80 seats and Maharashtra comes next at 48; Uttar Pradesh is not among the States named here, so Maharashtra heads this list. Note also that Rajasthan covers the greatest land area of these four States while carrying the smallest allotment, a reminder that seats follow population and not area.
