Option A: 'Raise' means 'to move to a higher level', 'to increase something'.
The word does not complete the meaning of the sentence.
Option B: 'Arouse' means 'to evoke or awaken'. This is the word most appropriate to the sentence, as suspicion is awakened. Actions awaken suspicion, they do not increase or create it.
Option C: 'Jack up' means 'to increase sharply'. This word does not seem relevant here.
Option D: 'Create' means 'to bring something into existence'. This word, too, does not bring a clear meaning to the sentence.
Since we need to choose the most appropriate word, 'arouse' is the right answer. Option B is correct.
Options A, C, D are incorrect as the words are not relevant in meaning.
