About this MCQ
This Easy General Science and Nature MCQ checks one syllabus fact.
The question is: “What is the name for the basic unit of matter, consisting of a nucleus of protons and neutrons surrounded by electrons?”
The accepted answer is D. Atom. Atom is the fact required by “What is the name for the basic unit of matter, consisting of a nucleus of protons and neutrons surrounded by electrons” (option D). Option A (“Human Skeleton”) does not match the stem; it is a near-miss used to catch incomplete recall of Atom. Option B (“Ostrich”) does not match the stem; it is a near-miss used to catch incomplete recall of Atom. Remaining alternatives (Speed of Light) fall outside the same rule and should be eliminated once Atom is identified. General Science and Nature questions of this type reward precise definitions rather than approximate associations. General Science and Nature recall of this distinction is a regular item in FPSC, PPSC, NTS, and CSS papers.
