$$m(t)=-0.0274(\frac{t}{7}{)}^2+7.3873(\frac{t}{7})+75.032$$

The function $m$ gives the predicted body mass $m(t)$, in kilograms (kg), of a male giraffe $t$ days after it was born in a wildlife reserve, where $t\le 390$. Which of the following is the best interpretation of the statement ‘$m(140)$ is approximately equal to $212$‘ in this context?

A

The predicted body mass of a male giraffe was approximately $140$ kg $212$ days after it was born.

B

The predicted body mass of a male giraffe was approximately $212$ kg $140$ days after it was born.

C

The predicted body mass of a male giraffe was approximately $212$ kg $\frac{140}{7}$ days after it was born.

D

The predicted body mass of a male giraffe was approximately $\frac{140}{7}$ kg $212$ days after it was born.
