It's possible, but not the only possibility. Therefore you can't
answer A.
And if you're not certain, you can't answer the question. Because
this is the Oracle OCP exam. The thing that you've studied
night and day for. Everything you learned in the two-night class
preparing you for database administration and nuclear physics. This
is crunch time, baby - right or wrong? You make the call. Pressure's
on. Which will it be? What if this is the question that
will put me under that passing grade. A or C? A or C?
Which will it be? What will I do????? You want the truth?
You want the truth? You can't handle the truth!!!!!!!!!!!!!
I'm heading back to the espresso machine now...

that it could be only 2 teachers get a raise, if the same 2 teachers teach

in the where clause, the IN says "any teachers that are in any of these
subjects. Since there are two subjects in the IN set and at least 2 teachers
have to teach each subject, 2*2=4. Basic mathematics: at least 4 teachers
will get a raise.
