Q.The District Industries Centre (DIC) is best described as:
(A) The apex bank for small industry in the country
(B) A single-window agency at the district level for small and village entrepreneurs
(C) An export-promotion body
(D) A body that only develops industrial infrastructure

The DIC's defining feature is that it brings many services together in one place, close to the entrepreneur.

Section g explains that the District Industries Centre (DIC) programme was launched in 1978 to provide all the services and support needed by small, tiny, and village entrepreneurs under a single roof at the district level. Each district has a DIC, which acts as the focal point (single-window agency) for the development of small and village industries in that district. This makes option (B) correct.

The DIC handles registration of units, guidance on selecting a product and preparing a project report, help in obtaining loans, subsidies, raw materials, and machinery, marketing assistance, and training — all from one place, so the entrepreneur need not run from office to office. …

Do not narrow the DIC down to one function. Its whole point is that it is a 'single window' bringing together registration, finance help …
