Initialize the three variables a , b , and c with 5 , 10 , and "I am a" respectively so that they will not be undefined .

You should be initialising the variables at the top of the page, where the comments tell you to. Once variables are declared (with var, let or const), you shouldn’t re-declare them.
Also, you should be initialising the variables with the values described above.
