In a crash safety test, engineers accelerate teo cars toward each other so that the fistance in meters between them is modeled by
[tex]d(t) = 25 - {t}^{2} [/tex]
, where t is time in seconds. What is the domain on which the model is applicable?

A.
[tex]0 \leqslant t \leqslant 25[/tex]
B.
[tex]0 < t < 5[/tex]
C.
[tex]0 < t < 25[/tex]
D.
[tex]0 \leqslant t \leqslant 5[/tex]
