Find the points in which the line $x=18+7t,y=-4-t,z=2t$ meets the coordinate planes. Describe the reasoning behind your answer.

How does the line $x=18+7t,y=-4-t,z=2t$ meet the coordinate planes?

A$.$ The line meets each coordinate plane when $t=0.$

B$.$ The line meets the $yz-$plane when $x=t,$ the $xz-$plane when $y=t,$ and the $xy-$plane when $z=t.$

C$.$ The line meets the $yz-$plane when $x=0,$ the $xz-$plane when $y=0,$ and the $xy-$plane when $z=0.$

D$.$ The line meets each coordinate plane at the origin.
