Why could the British manufacturers not recapture their old position in the Indian markets after the First World War?

The British manufacturers could not recapture their old position in the Indian markets after the First World War due to following reasons:
(l) They were unable to modernise and compete with the US, Germany and Japan.
(ii) The economy of Britain had crumbled after the war.
(iii) Cotton production had collapsed and exports of cotton cloth from Britain fell dramatically.
(iv) Within the colonies, local industrialists had gradually consolidated their position substituting foreign manufacturers and capturing the home markets.
