In B, C and D, airline executives are convinced, just as one-third of bank customers still prefer seems to compare how executives are CONVINCED to how customers STILL PREFER.

eg. his apple is bigger than mine. 而不是 than that of mine

convinced of sth 核心词就变成sth，比如A里面的social work education, 而本题的句意应该是确信一件事情，因此用that引导。
