74

One of the great things about the internet is that they are able to judge your level of intelligence simply by slightly obscuring a double-digit integer in a circle of red dots and giving you a multiple-choice question as to what that number is.

The correct answer is 74. If you got that right you are very intelligent.
If you said 75, it's good but not right and therefore moderately intelligent.
86 would put you just below average and 94 is off-the-scale cast-iron eedgit.
