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.
Answer:
The pectoralis muscle moves the front limb inward and the transverse abdominal muscles moves the posterior limiting membrane up. The limbs are brought into the shell, pushing up on the lung, causing air to expel by the muscles contracting.
To Breathe air in, the serrates muscle pulls out, the abdominal oblique pulls down and the weight of the viscera allows air to flow in, via negative pressure.
