D(b) is a function that models the population of deer based on the number of bobcats in an area. What is an appropriate domain for this function?

Responses
A D = {all integers}D = {all integers}
B D = (all real numbers}D = (all real numbers}
C D = {rational numbers}D = {rational numbers}
D D = {all whole numbers}

B D = (all real numbers} - Since the population of deer can vary based on the number of bobcats in an area, the domain should include all real numbers to account for any possible values of bobcats.
