问题如下：
Cliff was invited to give a speech at an important financial conference, the host of the event is an investment manager who recently carrys on business with Cliff's firm. To show high respect for the speakers, the host firm provided Cliff with free conference registration for his wife and arranged for fancy seafood dinner at the local lavish restaurant after the conference. Which of the following statements is the most appropriate?
选项：
A. Cliff can not accept the invitation because the free conference registration for his wife and the seafood dinner will violate Standard I(B).
B. Cliff can not accept the invitation because the seafood dinner will violate Standard I(B).
C. Cliff can accept the invitation thoroughly.
解释：
A is correct.
Based on Standard I(B) Independence and Objectivity, members and candidates must maintain their independence and objectivity. The free conference registration for Cliff's wife and the fancy seafood dinner do not have direct relation with the speaking engagement, and can be regarded as inducements that affect his independence and objectivity. If Cliff accepts the invitation, he will violate Standard I(B).
老师，这道题哪里看出来cliff是个researcher或者analyst，而不是manager呢？
