No problem. I've looked over your sentences and I have three comments. :D
A. He is
without a job. (Adjective)
Note, if 'without a job' were a location, then it would function as an adverb. Note also, the only linking verb that can have
an adverb of place as its subject complement is the verb To Be and its forms (i.e., is, am, are, etc.) :D
Note also, linking verbs, and that includes the verb To Be, can never be modified by an adverb of manner. Only action verbs can be modified by adverbs of manner. :wink:
B. She managed to keep her children
off cigarettes. (Object Complement)
Note, TEST: her children
are off cigarettes. :D
C. She is respected
by her students. (Semantic Subject; Passive)

By the way, linking verbs are
linking verbs, not intransitive verbs. Also, SC stands for Subject Complement, of which there are two kinds: predicate adjectives and predicate nominals/nouns. I am not familiar with the forms
Cs and
As. Sorry.

Moreover, DO stands for direct object and IO for indirect object. :D
All the best, :D
