A closed rectangular box has dimensions of length n inches, width n+4 inches, and height n+5 inches. Write a polynomial function $A(n)$ for the area of the largest side of the box if dimensions increase by 6 inches.

A) $A(n)=n^2+4n-116$
B) $A(n)=n^2-11n+110$
C) $A(n)=n^2+4n+110$
D) $A(n)=n^2+21n+110$
E) $A(n)=n^2+11n+110$
