Ans A

if params in the function are:
Function Person(firstName, lastName, eyecolor)
The answer is A
if params in the function are:
Function Person(firstName, lastName, eyeColor)
The answer is C

Option C is correct

The output after the code executes is undefined.

This is because the property job is added to the Person constructor function object itself, not to the prototype object that will be used to create instances of Person. When you access myFather.job, it is not found in the instance's prototype chain and therefore returns undefined.

the correct answer should be A, since Javascript is case sensitive and the param eyecolor is written all in lower case meanwhile inside the constructor is trying to assign eyeColor (camelCase).
