Solution
Answer: Option B
Solution:
The indicator plant for fluoride pollution is Gladiolus.The most widely used fluoride bioindicator is Gladiolus. This plant is showing typical fluoride injury. Varieties differ enormously in sensitivity and cultivation also seems to affect response.
The use of Gladiolus plants was an effective biomonitoring technique for assessing the impact of atmospheric fluoride concentrations near a small-scale, poorly managed brick kiln in South Asia.
