Answer:
Option C, dP/dt=1/5P
Step-by-step explanation:
The change is population of insects is directly proportional to the rate of change of population
Hence,
Or 
where K is the proportional constant
We will find the value of k
Keeping the given values of rate of change of population and population in above equation, we get -
Hence,
