Crop that is least tolerate soil acidity is

Answer: Option A

A crop that is least tolerant to soil acidity is Okra.
Okra is tolerant of a wide range of soil pH but prefers soil with a pH between 6.0 and 6.8. Soils at or below 5.8 can result in okra with poorly developed pods, as it cannot tolerate acidic soil i.e. soil pH below 6.
If the soil pH is below 5.8, it should be limed to increase the pH to 6.0 or more.
