Genetic diversity in agricultural crops is threatened by:

  1. A
    introduction of high yielding varieties
  2. B
    intensive use of fertilizers
  3. C
    extensive intercropping
  4. D
    intensive use of biopesticides.

Solution & Step-by-step Explanation

The widespread introduction and adoption of a few high-yielding varieties (HYVs) often leads to the displacement of numerous traditional landraces and wild relatives. This process, known as genetic erosion, significantly reduces the overall genetic diversity available in agricultural systems.
