The correct options are
B raise for discussion
C to rear or educate
A phrasal verb is a verb combined with an adverb or preposition (or both) to provide a variety of meanings. 'Bring up' has various meanings, like 'raise for discussion', for example, 'Do not bring up this topic'. It also means 'rear or educate', for example, 'she brought them up on her own'. Hence options B and C are correct. Option A does not provide the meaning of the phrasal verb, nor does option D, A provides for the meaning of 'bring on' and D explains 'bring out', hence A and D are incorrect.
