Answer: Option 'd' is correct.
Step-by-step explanation:
Since we have given that
Exponential function is a function whose value is raised or decreased exponentially.
So, Population growth is exponential function as it increases exponentially.
Compound interest is exponential function when it increases continuously.
Exponential decay is also an exponential function.
But Simple interest is not an exponential function as it does not increase with the power of the argument.
Hence, Option 'd' is correct.
