Jeb Bush Question

When they refer to Jeb Bush as "unbelievably brilliant", does this reflect:

a) a comparison with his elder brother, George?
b) that he's the first Bush with an IQ in the triple digits (101 is triple digits)?
c) that, unlike the governor of California, he can spell and pronounce his state's name?
d) that he does many of his daughter's drugs (she looks like every bit as much of a brain trust as the Bush twins and is supposedly just as much of a drug dolt)?
