The answer for your question is going to be C
Answer:
D). Iron Metal work.
Explanation:
Early agricultural life was dominated by a number of innovations like the invention of wheel that began transportation of humans from one place to another, pottery for storing grains, weaving, tools made of stone and wood, etc.
As per the question, 'iron metal work' would not be categorized as an innovation of early agricultural life as it began during late 11th century BC much later than the early agricultural life. Early agricultural life was highly commanded by domestic activities like farming, pottery, weaving, etc. and therefore, the innovations too were accordingly. Early people gradually discovered metals and learnt to use them later with time. Thus, <u>option D</u> is the correct answer.
