(d) If both the Assertion and Reason are incorrect.

Explanation:

Pollution may be defined as an undesirable change in physical, chemical or biological characteristics of air, water and land causing harmful effects on living organisms. Pollution can be natural or man made. Natural pollution includes volcanic eruptions, soil erosion, UV- rays etc. Pollution is different from contamination. Contamination is the presence of harmful organisms causing disease.
