Best answer
Correct answer is (d) Sodium arsinite

For explanation: Sodium arsinite is an herbicide. It is less persistent but toxic to mammals. It decomposes in a few months. Like organo-chemicals, this will also get concentrated in the food web. Some herbicides can also cause birth defects. Other examples of herbicides include diclofop, sodium chlorate, etc.
