Explanation:
Surface mining, including strip mining, open-pit mining and mountaintop removal mining, is a broad category of mining in which soil and rock overlying the mineral deposit are removed, in contrast to underground mining, in which the overlying rock is left in place, and the mineral is removed through shafts or tunnels.

Plants absorb water from the soil by osmosis. They absorb mineral ions by active transport, against the concentration gradient. Root hair cells are adapted for taking up water and mineral ions by having a large surface area to increase the rate of absorption.
Uptake occurs around the root tip, into epidermal cells with their associated root hairs and into cells in the outer layers of the root cortex.
Answer: Option B
Explanation:
Recycling the runoff from the irrigation system can be a sustainable practice. The word sustainable can be defined as the method which provides enough resources for today and keeps on saving the resources for the future generations as well.
The recycling of the materials can be considered as a sustainable practice as the left over can be recycled and the need of raw materials for the next process will be less than normal.
Recycling allows the extraction of useful material from the waste and using it and ensures it use again.
Hence, the correct answer would be Option B
