Correct answer: (d) Only 1
Explanation
- A
Neither 1 nor 2
Option (a) claims that neither statement 1 nor statement 2 is correct. This is incorrect because statement 1 is factually true.
- B
Both 1 and 2
Option (b) claims that both statement 1 and statement 2 are correct. This is incorrect because Borneo is not formed due to volcano deposition but is largely a continental landmass formed by ancient tectonic processes.
- C
Only 2
Option (c) claims that only statement 2 is correct. This is incorrect since statement 2 is false while statement 1 is true.
- D
Only 1
Option (d) states that only statement 1 is true, which is correct because Borneo is divided among three countries: Indonesia, Malaysia, and Brunei. Statement 2 is incorrect because the island is primarily of non-volcanic, Sundaland continental shelf origin rather than volcanic deposition.
Summary. Official key is (d) because Borneo Island is politically divided among three nations: Indonesia, Malaysia, and Brunei, making statement 1 correct. Statement 2 is incorrect as the island's geological formation is not primarily due to volcano deposition, unlike many other Indonesian islands. Candidates often confuse the geological origins of Sundaland fragments with volcanic island arcs. Thus, only the first statement holds true. Therefore, option (d) is the right answer.
