Which of the following could cause a habitat change?

Which of the following could cause a habitat change?

a. introduction of an invasive species
b. a wildfire
c. a mudslide
d. all of the above

The answer is D. All of the above

Definitely all of the above. If A is the case, you have your new habitat there, if B is the case than all of the lifeforms there will get out of that habitat and if C is the case than the mudslide (depending on the magnitude of the slide) can cause change in topography and there will be a potential for a new habitat.
Hope this helps.

All of the above is the correct answer.
