Hi !
a dependant clause = first one
includes a subject and a verb but cannot stand alone as a complete thought
a complex sentence = the third one
Because the monster jumped up without warning, the girl screamed
1 = compound
2 = simple
3= complex : an independent clause + a dependant one
4 = compound
hope I helped !
