Explanation:
Symbolism always plays a vital role in attaching a deeper meaning to the text using an object, idea, or people as the symbol. In the given excerpt, the 'windmill' is used as a symbol of 'technology' which suggests the 'need and significance of industrialization in the economy' as it would help 'operate a dynamo', 'light the stalls and warm them in winter', 'run a circular saw, a chaff-cutter, a mangel-slicer, and an electric milking machine' by supplying electricity to the farm. Thus, option B is the correct answer.
