we can solve it by verifying options.

Option A) $(CA)^+\rightarrow CABE$

Option B) $(AB)^+\rightarrow AB\rightarrow ABC\rightarrow ABCE$

Option C) $(BD)^+\rightarrow BDE$

Option D) $(AD)^+\rightarrow ABD\rightarrow ABCD\rightarrow ABCDE $

So this option covers all the attributes, unlike others.

Option (D) is correct.
