Consider the following recursive method.

publ ic stat ic boolean recurMethod$($St r ing st r$)$

$\{$

i f $($st r $.$ length$()<=1)$

$\{$

return t rue;

$\}$

else i f $($st r $.$subst r ing$(0,1).$compareTo$($st r $.$subst r ing$(1,2))>0)$

$\{$

return recurMethod$($st r $.$subst r ing$(1))$ ;

$\}$

else

$\{$

return false;

$\}$

$\}$

Which of the following method calls will return t rue $?$

$($A$)$ recurMethod$("$abcba$")$

$($B$)$ recurMethod$("$abcde$")$

$($C$)$ recurMethod$("$bcdab$")$

$($D$)$ recurMethod$("$edcba$")$

$($E$)$ recurMethod$("$edcde$")$
