The correct option is A Rope making
Cottage industries are small manufacturing units where artisans use local raw materials and simple tools to produce everyday goods usually in their homes with the help of their family members or part-time labour. Rope-making is a common cottage industry in India. This is where a family works together from their home. They actually work outside, somewhere with plenty of space to stretch out the lengths of rope and preferably with shade, like under big trees.
