to modify "her husband" => "whom was" is incorrect => supposed to be "who" => A out

"he was" => make the sentence becomes 2 independent clauses without conjunction => C out
E. The artist had drawn a beautiful portrait of herself and her husband, standing and smiling at the camera standing beside her, smiling at the camera.
"standing and smiling at the camera standing beside her" is totally akward. the role of "standing beside her" is ambuigious

B and D
B. The artist had drawn a beautiful portrait of
herself and her husband, who was standing beside her, smiling at the camera.
D. The artist had drawn a beautiful portrait of
herself and her husband; he were standing beside her, smiling at the camera.
main verb "had drawn" in past perfect tense implies that there is another action occurred after the "had drawn"
"who" is ok but "who was" make the "standing" action happen after the "draw" action => doesnot make sense
"he were" -> kind of hypothesis. she imaged if he were standing beside her and drawn a portrait => make more sense
