Correct asnwer is: b)No, height is not a function of weight because two students weigh 165 pounds but have different heights.
Solution:-
The definition of a function is for every input, function must have a unique output.
Here weight is input and height is output.
So for input=weight =165 pounds, we have 2 values of output that is 172cm and 163cm.
Hence height is not a function of weight.
