A unit will evaluate all employees at the end of the year, and there are five awards, including the best professional award, the best creative award, the best collaboration award, the best writing award, and the star award of the year. The annual star award can no longer select the best creative award and the best professional award; if the collaborative award is selected, the writing award can no longer be obtained; if the professional award is selected, the collaborative award can no longer be obtained. Each person can get up to two awards There are a total of 3 employees in the Comprehensive Department, all of which have won all awards, but each award is different. It is known that Employee A received the Star Award, and some of Employee B and Employee C received the Writing Award. It follows that the following guess must be correct? ['If B wins the writing award, he also receives a professional award.', 'If B wins the collaboration award, B and C each receive two awards.', 'If B wins the Writing Award and the Creativity Award, then A must receive only one award.', 'If C wins the collaboration award, then B must not win the professional award.']
