The answer is B., Natural Selection.
Weather certainly doesn't change populations, and genes only caused individuals in a population to be slightly ( genetically-wise ) different from the others. It does cause change, but not change in the whole population over time.
Natural disasters don't change the populations over time either. Natural disasters only caused change in their environment, at most.
So, the only answer left is natural selection, and it makes sense too!
Natural selection is the process where the individuals with better traits suited to survive in that specific environment live on and give those good traits to their offspring.
The individuals with less suited traits to survive will die out, and will not be given an opportunity to reproduce and pass on their less suited traits, so over time, the population will increase of individuals with better suited traits to survive and the individuals with less suited traits will eventually die out, therefore making the entire population change.

I’m pretty sure it’s convergent
A uniform region occupies an area based on a homogeneous characteristic is a true statement. Regions can also be based on ecological features and as well as the location of it region itself.

The decline in the overall population of trout and larger fish is because the Insect population has decreased.
<h3>What is a population?</h3>
A population is a group of organisms of the same species living in the same habitat.
Population of organisms is affected by;
- availability of water
- space
- food and nutrients
- predators
- climate change
Since the population of trout is directly affected by the number of insect species, the decline in the overall population is because the Insect population has decreased.
