Hint: Hindustan Vanaspati Manufacturing Co (now Hindustan Unilever Limited) until the early 1930s imported Hydrogenated vegetable oil available in India. Dalda, the new brand name was born when Hindustan Vanaspati wished to start manufacturing hydrogenated vegetable oil locally, and hence as a result Dalda was born. It was introduced in 1937 and has become one of the longest-running brands in India.
Complete step-by-step solution:
Depending on the type of raw materials used Industries may be agro-based, mineral-based, marine-based, and forest-based. The type of industries that use plant and animal-based products as their raw materials are known as Agro-based industries. Vegetable oil, food processing, cotton textile, leather industries, and dairy products are examples of agro-based industries. The Dalda brand was the first national and purely Indian brand of vanaspati. The hold of this brand was such that it became a household name in kitchens across the country. In those days, Ghee and coconut oil used to be the favorite frying and cooking mediums in households. The common man couldn’t afford them on a regular basis since they were expensive, especially ghee. The hydrogenated highly saturated fat/oil was introduced first by Dutch traders into India. This easy-to-use, cheap, and tasty cooking medium soon became very popular. Then Hindustan Vanaspati Manufacturing Company (at present Hindustan Unilever limited) was incorporated by the Lever brothers in 1931 for producing vanaspati ghee in India. Thus, a factory was established at Sewri in Greater Mumbai, and then in 1937, the Dalda brand was introduced to sell Vanaspati.
Thus, option (A) is correct.
Note: The main style of hydrogenated vegetable oil is commonly designated generically as “vanaspati ghee” since Hindustan Vanaspati's “Dalda” product came to be synonymous with the genre.
