Solution
The correct option is C Genetic stability can be maintained
Self-pollination maintains the existing genetic traits and do not introduce any new traits in the progeny.
So, it maintains the genetic stability but makes the progeny weaker and less adaptable to the climatic variations as no new traits are introduced in the progeny. Hence, the correct answer is C.
