According to me it should be

$c<\cdotp g$

AaBcD

in some step of derivation if we use D--> g  then string will be   ____cg

it fulfill the condition for $c\dot <g$   as c appears first then g appears... And more over g is at the lower level of production than c.  (I'm not sure whether this sentence makes any sense according to the question or not )
