The pH value from 7.0 to 7.5 is considered neutral. pH value over 7.5 is alkaline.
pH value less than 7.0 is acidic.
Soils with a pH of less than 5.5 are considered strongly acidic.
pH value less than 7.0 is acidic.
Soils with a pH of less than 5.5 are considered strongly acidic.

Alkaline soils are characterized by elevated concentrations of exchangeable sodium ion (>15%), free carbonate and bicarbonate, low calcium, high pH value (8.5-10).

Option C is also correct please review.
1-6.9 (Acidic).
7.0 (Neutral).
7+ (alkaline).
1-6.9 (Acidic).
7.0 (Neutral).
7+ (alkaline).
