The branch of science which deals with a living being is called biology.
The correct answer is A
To solve this question, we have to change the units into km.
The rate of moving plate is given in cm/year that is 3cm/year. In km, we have to divide it by 1000000.
After diving it, we will get 0.00003km/year.
Now use the simple distance formula and divide the total distance by the unit distance.
[tex]\frac{1500}{0.00003}[/tex]
After solving it we will get option A that is 50,000,000 years.
Hence, option A is correct.
