The correct answer is option 3. This statement is not correct because it states that the rate of increase in onion production is more than potato production in the current year compared to the previous year. However, there is no information provided about the rate of increase in onion and potato production, so we cannot determine whether this statement is correct or incorrect based on the given information.

Option 1 states that the area under horticulture crops has increased compared to the previous year. This means that more land was used for growing horticulture crops in 2016-17, indicating a potential growth in the horticulture sector.

Option 2 states that fruit production during the current year is higher than the previous year. This suggests that there has been an increase in fruit production in 2016-17, indicating growth in the fruit sector.

Option 4 states that the major tomato-growing states in India are Madhya Pradesh, Andhra Pradesh, Karnataka, Odisha, and Gujarat. This information provides a list of states where tomato cultivation is concentrated.

In summary, the only statement that is not correct is option 3, as it lacks sufficient information to determine its accuracy.
