Explanation:

The passage speculates on why Bernie Madoff’s wife and sons did not flee the country but does not come to a definite conclusion. Option 1 can be ruled out from the lines “ … the public outcry against Ruth Madoff and her sons began almost from the instant of Madoff’s arrest and did not cease By the time he pleaded guilty, it was deafening.” We can thus, infer from the passage that Madoff’s family could have fled between the time he was arrested and before he pleaded guilty. This eliminates option 1.
Option 2 can be eliminated from “ … his two sons, if they were guilty, had the opportunity, the means and the motive to flee.”
Option 3 can be ruled out from “ … they could turn him in and deflect … if the sons were actually guilty.”
Thus, none of the options is suitable.
Hence, the correct answer is option 4.
