ANSWER
The correct answer is option C.
EXPLANATION
In order to determine which ordered pairs are generated by an exponential function, we examine the y-coordinates to see which one has a constant ratio.
As for the first ordered pairs,

These ordered pairs cannot be generated by an exponential function.
For the second option also,

These ordered pairs too cannot be generated by an exponential function.
For the the third option,

Therefore these ordered pairs were generated by an exponential function.
The fourth option too,

The ordered pairs could not be generated by an exponential function.
