The correct example of disruptive selection is **d) birds with medium sized beaks are less successful than those with either small or large beaks**.
Disruptive selection occurs when individuals at both extremes of a trait distribution have higher fitness than those in the middle, leading to a preference for the extreme traits and potentially resulting in speciation over time. In this case, birds with medium-sized beaks are at a disadvantage compared to those with small or large beaks.
