Options
The correct answer is A.
Explanation:
The question is asking about the pH level of a soil sample that has a pH of 4.5. The options given are Acidic, Alkaline, Neutral, and Fertile.
pH is a measure of the acidity or alkalinity of a substance. A pH value below 7 is considered acidic, a pH of 7 is considered neutral, and a pH value above 7 is considered alkaline.
In this case, the soil sample has a pH of 4.5, which is below 7. Therefore, the soil sample is acidic.
Acidic soil can affect plant growth and nutrient availability. Some plants prefer acidic soil, while others thrive in more neutral or alkaline soil. It is important for farmers and gardeners to understand the pH level of the soil in order to choose the right plants and apply appropriate soil amendments if necessary.
So, the correct answer is Option A: Acidic.
