B Correct answer
Explanation

'Every' distributes to each item individually, so even when multiple nouns are joined by 'and' after 'every,' the subject remains grammatically singular. 'Every possible cause and suspect' means each cause and each suspect separately, so the singular verb 'was' is required, not 'were.'
