Answer:
A) scapegoats and being blamed for John's grades
Step-by-step explanation:
There is no scientific proof that female Professor teach better or worse than their male counterparts or are not smart enough as they have got a doctorate so they must be smart and intelligent in that field. Also, it cannot be said that they are being discriminatory or prejudiced towards John as in that case all male or similar ethnicity students would have failed in both courses. The most logical conclusion in this case is that John is trying to make the female Professors a scapegoat and is blaming them for his own bad grades and bad academic performance.
