The correct answer is option 4: 1, 2, and 4 (Wheat, Paddy, and Sugar).
To estimate food inflation in India, certain goods are included in the calculation. In this case, the goods that are included are wheat, paddy, and sugar.
Wheat is an important staple food in India and its price fluctuations have a significant impact on overall food inflation. Paddy, which is the main crop used to produce rice, is another essential food item in India. The price of paddy also contributes to food inflation. Sugar, a commonly used sweetener, is also included as its price fluctuations can affect the overall food inflation.
Option 1 is incorrect as it does not include sugar. Option 2 is incorrect as it includes tobacco instead of wheat. Option 3 is incorrect as it includes paddy and sugar, but not wheat.
Therefore, the correct answer is option 4: 1, 2, and 4 (Wheat, Paddy, and Sugar).
