$3^{2}=9$
$5^{3}=125$
$9\neq25$

Ignore

[B]
$3^{2} = 9$
$9 \ \textgreater \ 3$
Yes

$3^{3}=27$
$4( 3^{2})=36

27 \ \textless \ 36$
Yes

Therefore
$x=3+2=5$

[C]
$4^{5}=1024

 5^{4}=625

1024\ \textless \ 625$
No

$5^{5}=3125

 5^{5}=3125

3125\ \textgreater \ 3125$
No

Ignore

[D]
$5^{5}=3125

 2^{5}=32

3125\ \textgreater \ 32$
Yes

$5^{2}=25
25\ \textless \ 11$
No

Therefore
$x=5+8=13$

[E]
$8\ \textgreater \ 7$
Yes

Therefore
$x = 13^{2}=169$
