The decimal system reaching the world from India is what type of contribution?

Answer and explanation

Correct answer: Scientific and mathematical contribution

Direct answer: Option B, scientific and mathematical contribution. The decimal system is a method of writing and calculating numbers, so it belongs to mathematics and scientific knowledge. Step by step: people use place value, such as ones, tens, hundreds, and so on; the decimal idea makes large calculations easier; this knowledge travelled from India to other parts of the world and became widely used. Option A is wrong because a political boundary separates territories and is not a number system. Option B is correct because the decimal system is mathematical knowledge shared with the world. Option C is wrong because a coastal line is a geographical boundary near the sea. Option D is wrong because a vegetation list describes plants, not methods of calculation. Remember: numbers, zero, place value, and calculation point to mathematics, not geography or politics.
