A change occurred in the genetic variability. The deer population experienced a rapid decline due to a parasite. Mountain lion hunting experienced an increase in restrictions. The population of Trichinella, a parasite, experienced a decline.

Answer 1

A mountain lion population recently experienced a drop in population size. The best limiting factor that is involved is- The deer population experienced a rapid decline due to a parasite.

Only this could be the best possible answer out of all other options because when there are no deer, there is no food for the lions.

Answer 2

The correct answer is option B, The deer population experienced a rapid decline due to a parasite

Step-by-step explanation:

As the prime food of lion in the jungle is deer, so if the population of deer is to be considered as declining , there will be some certain amount of negative impact on the population of lion as well.

The parasite attacking the deer causes their death , due to which very few deer are available as food to the lions thus the lions reach a stage of starvation after a certain period of time . In absence of food they may start dying as well thus the factor "The deer population experienced a rapid decline due to a parasite" is a limiting factor.
