Since we were given only one point, we have to test each exponential function for the point 

Since exponential functions are of the form 

, The correct option is between option A and option C.
For option A, 

On substitution, we have; 



.
Since the point satisfied the exponential function 

, the exponential function goes through it.
Hence the correct answer is option A.
No need to test for option C again.
