↪Actually welcome to the concept of the completing square ..

↪Basically during this method , we have to generate a term and have to add that on the both sides to get a whole sqaure ..

↪thus the 3rd term is given as

↪=》 ( 1/2 * coefficient term of the "x")^2

↪thus here in the above equation this term would be as

↪=》 ( 1/2 * 4)^2 = (2)^2 = 4

↪But the Carly has added the term 16 , which is totally wrong , thus the option D.) is correct

↪D.) She added the wrong value to both the sides of the equation to complete the square
