Option 1 -> In FPTP, each constituency elects only ONE representative, not multiple.
Option 2 -> In FPTP, voters vote for individual CANDIDATES, not directly for parties.
Option 3 -> This describes proportional representation, not FPTP. In FPTP, seats are not allocated proportionally.
Option 4 -> In FPTP, the candidate with the most votes (plurality) wins, even without an absolute majority (50%+1).
Hence, Option 4 -> In the First Past the Post system, a candidate needs only a plurality (more votes than any other candidate) to win, not necessarily a majority. For example, in a three-way race with vote shares of 40%, 35%, and 25%, the candidate with 40% wins despite lacking the 50%+1 majority -> correct
