Solution

The correct option is B If both assertion and reason are false
  • The chemicals used to eliminate pests are called pesticides.
  • Pesticides include insecticides (for killing insects), weedicides (for killing weeds), rodenticides (for killing rats) and fungicides (for killing fungi).
  • So, all pesticides are not only insecticides.
  • Pesticides do not add any essential nutrients to the soil.
  • So, both the assertion and reason are false.
