Several years ago, the wild rabbits of Australia were seriously threatened by a virus that was accidentally released into their population. Suppose that the following table gives the number $r$ of rabbits (in millions) remaining $t$ months after the release of the virus.

Use a calculator program to find the linear regression line for this data. What is the physical interpretation of the $t$-intercept?
A) The decrease in the population if the virus is present an additional month.
B) The number of months the virus took to lower the population by 1 milllion.
C) The initial rabbit population when the virus was introduced.
D) The time in months at which the rabbit population falls to zero.
