In order to complete this analogy, let's first observe the relationship between the first two words. Paranoid and suspicious mean similar, if not the same thing, which means they are synonyms. So, in order to complete the analogy, we need another pair of words that have the same meaning.
Therefore, the correct answer is timid and shy because they represent the same thing whereas the other options do not: hatred/affection are antonyms, as well as trust/distrust; intelligence and brilliance do not necessarily mean the same thing as someone can have low intelligence.
