(B) A series of inventions improved each stage of production, increased output per worker, and enabled the manufacture of stronger threads, boosting the cotton industry's capacity.
The passage explicitly states: "A series of inventions in the eighteenth century increased the efficacy of each step of the production process… They enhanced the output per worker… and they made possible the production of stronger threads and yarn." This directly caused higher demand for raw cotton. Option B matches this explanation from the source. The other options introduce points not supported by the passage (e.g., East India Company subsidies, wool industry decline, or government bans on finished cloth imports).
