Due to high rainfall, soils in Meghalaya tend to be:

The correct answer is: b) Acidic and leached.

The high rainfall in Meghalaya causes the soil to be acidic and leached. This is because the rainwater dissolves the minerals in the soil, carrying them away. This leaves the soil with a higher concentration of acids, which can make it difficult for plants to grow.

The other options are incorrect because:

• Option a) is incorrect because the high rainfall does not make the soil highly fertile. In fact, it can make it difficult for plants to grow.
• Option c) is incorrect because the high rainfall does not make the soil alkaline and saline. In fact, it can make the soil acidic.
• Option d) is incorrect because the high rainfall does not make the soil rich in organic matter. In fact, it can leach away the organic matter in the soil.

I hope this helps! Let me know if you have any other questions.
