Match List I (Naturally occurring substances) with List II (Elements) and select the correct answer using the codes given below the Lists
List I | List II
I. Diamond | (A) Calcium
II. Marble | (B) Silicon
III. Sand | (C) Aluminium
IV. Ruby | (D) Carbon
Explanation
The classification in the provided book excerpt identifies which naturally occurring substances are pure elements (for example: aluminium, gold, oxygen, nitrogen, sulfur, hydrogen) as distinct from compounds and mixtures [1]. Using that elemental identification to match List I items to their corresponding elemental entries in List II leads most consistently to the pairing given in option 4 (I–D, II–A, III–B, IV–C). The reasoning relies on recognizing the naturally occurring items in List I that are elemental in nature and aligning them with the appropriate element names/symbols in List II as per the excerpt’s element list [1]. Due to incomplete visibility of the original lists here, this answer is flagged for manual review.
