The correct option is C Deindustrialisation
India was extremely poor as a result of steady deindustrialisation by the British government. The economy in India was mainly characterised by the blend of agriculture and handicrafts. However, the British government gradually stopped traditional handicraft industries. This process came to be known as deindustrialisation, a term that means the opposite of industrialisation. Hence, post independence, all economic planning was done with the objective of first reviving agriculture and industries.
