Show Hint
Effects of waterlogging:
\[
\boxed{
\text{Soil pores filled with water}
\rightarrow
\text{Low oxygen}
\rightarrow
\text{Poor root respiration}
\rightarrow
\text{Reduced crop yield}
}
\]

- Salinity buildup
- Oxygen deficiency in roots
- Soil erosion
- Low rainfall
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Waterlogging fills the soil pores with water, reducing the availability of oxygen to plant roots.
The resulting oxygen deficiency impairs root respiration and decreases crop growth and yield.
Hence,
\[
\boxed{\text{Oxygen deficiency in roots}}
\]
is the correct answer.
Therefore,
\[
\boxed{(B)}
\]
