Final answer:
The British improvements such as infrastructure, legal system, and initiation of industrial development contributed to India's post-independence advancement in communication, trade, legal justice, and economic growth.
Step-by-step explanation:
After gaining independence from Great Britain, the British improvements in infrastructure such as railways and telecommunication systems continued to benefit India by facilitating internal communication and trade. Additionally, the legal system established by the British, promoting justice for all, provided a foundation for India's own legal system, aiding in maintaining peace and order.
Moreover, the introduction of industrial development and entrepreneurship during the colonial period set the stage for India's post-independence economic growth, exemplified by individuals like Dwarkanath Tagore who invested in ventures such as coal mines and textile factories.
