Answer: Option A

Solution(By Examveda Team)

Calcium and magnesium can be deficient in Acidic soils.
Acid soils are those that have a pH value of less than 5.5 for most of the year.
Soil acidification is the buildup of hydrogen cations, which reduces the soil pH. Acidification also occurs when base cations such as calcium, magnesium, potassium, and sodium are leached from the soil.
