Which of the following describes environmental parameters that are most important to consider prior to building a housing development?

The answer is: B. The impact that clearing the land would have on local wildlife. Sometimes when people try to make space to industrialize and such, wildlife could be negatively involved. D is kinda true except I think that every decent housing development should have been built adequately-enough so that it can withstand the usual amounts of rain, snow and other types of precipitation that the area commonly encounters. A has nothing to do with the environment but the amount of space the housing would require. C talks about an economic issue, not an environmental one. So yeah, the answer is B.

I think you might be looking for : the impact that clearing the land would have on the wildlife.

You SHOULD have included the options in the question.
