Which of the following industries was most affected by the 'deindustrialisation' of India in the 19th century?

The 'deindustrialisation' of India in the 19th century refers to the decline of traditional Indian handicrafts and small-scale industries due to British colonial policies and the influx of cheap machine-made British goods. The cotton textile industry was the most severely affected — India had been a global leader in handloom cotton textile exports for centuries, but the flooding of Indian markets with mill-made cotton goods from Manchester and Lancashire, combined with discriminatory tariffs and the destruction of traditional weaving centres, devastated millions of Indian weavers and artisans. Silk, iron and woolen industries were affected but to a lesser degree than cotton textiles.
