Show answer & explanation
Correct answer: C
Concept — four standard results
A cuboid always has 12 edges (three sets of four parallel edges).
The interior angles of an n-sided polygon sum to (n − 2) straight angles = (n − 2)π radians.
An n-sided polygon has n(n − 3)/2 diagonals.
A prism built on a k-sided base has k + 2 faces (two base faces plus k lateral faces).
Applying each to List – I
Cuboid → 12 edges → the List – II value 12, i.e. item 3.
Heptagon (n = 7) → angle sum = (7 − 2)π = 5π radians → the value 5π, i.e. item 4.
Hexagon (n = 6) → diagonals = 6(6 − 3)/2 = 9 → the value 9, i.e. item 1.
Triangular prism (triangular base, k = 3) → faces = 3 + 2 = 5 → the value 5, i.e. item 2.
Cross-check
The pairing is A → 3, B → 4, C → 1, D → 2, i.e. the code 3 4 1 2 — the only code in which every List – I quantity equals its List – II value.
