  2. BSodium chlorate and Aldrin
  3. CSodium arsinate and Dieldrin
  4. DSodium chlorate and sodium arsenite.

Correct answer

D. Sodium chlorate and sodium arsenite.

Step-by-step solution

Herbicides, also commonly known as weedkillers, are chemical substances used to control unwanted plants. Selective herbicides control specific weed species, while leaving the desired crop relatively unharmed, while non-selective herbicides can be used to clear waste ground, industrial and construction sites, railways and railway embankments as they kill all plant material with which they come into contact.

Nowadays, the pesticide industry has shifted its attention to herbicides such as sodium chlorate (NaClO3)\left({NaClO}_{3}\right), sodium arsinite (Na3AsO3)\left({Na}_{3}{AsO}_{3}\right) and many others.
