Answer is Wrong!
Answer is Right!
The correct answer is C. 6-7.
A pH of 6-7 is considered neutral, which is the ideal pH for most plants. A pH below 6 is acidic, while a pH above 7 is alkaline. Soils with a pH that is too acidic or alkaline can make it difficult for plants to absorb the nutrients they need to grow.
Option A is incorrect because a pH of 3 is too acidic. Option B is incorrect because a pH
of 9 is too alkaline. Option D is incorrect because a pH of 14 is extremely alkaline.
