In India and the world, the decimal system is an example of what?
Answer and explanation
Correct answer: Spread of mathematical knowledge
The decimal system is a mathematical contribution associated with India’s intellectual history. Its place-value structure makes it possible to represent numbers efficiently and perform calculations more easily. Knowledge of this kind can travel between societies through learning, teaching, translation, writing, and contact between regions. In the context of India and the world, it shows that ideas and knowledge moved beyond their place of origin.
Option B is correct because the decimal system represents the spread of mathematical knowledge. The other choices do not describe a mathematical idea: a trade spice is a commodity, while a sea coast and a land boundary are geographical features. The question is therefore testing cultural and intellectual exchange, not physical geography or trade goods. The answer should be connected with India’s contribution to mathematics becoming known more widely.
