Answer
$C$
Work Step by Step
In order to get the solution we will take the help of conversion the factors.
As we know 1 hour= 60 minutes, 1 day=24 hours and 1 year =365 days.
$\frac{8 \space Babies}{1 minute} \times \frac{60 \space minutes}{1 hour} \times \frac{24 \space hours}{1 day} \times \frac{365 \space days}{1 year}$
$=4204800$
Hence, the correct answer is $C$.
