Select the correct answer from the code given below:
Only 1
Both 1 and 2
Only 2
Neither 1 nor 2
Correct Answer: A
Detailed Solution
Statement 1 is correct. Borneo is a large island of South-East Asia and its territory is divided among three countries—Indonesia, Malaysia and Brunei Darussalam. The Indonesian part is generally known as Kalimantan, while the Malaysian states of Sabah and Sarawak are situated on Borneo. Brunei is also situated on the north-western coast of Borneo.
Borneo is the third-largest island in the world and is regarded as the largest island in Asia. The largest share of the island belongs to Indonesia.
Statement 2 is incorrect. The origin of Borneo cannot be attributed simply to volcanic deposition. Its geological structure is highly complex and developed through prolonged tectonic processes involving continental blocks, plate movements, subduction, collision, sedimentation, faulting and uplift. Volcanic and igneous rocks do occur in parts of Borneo, but the entire island was not formed by volcanic deposition.
