Fill in the gap with the most appropriate option from the list following the gap.

Until his recent experience, Onimisi used to pride himself _____ his fearlessness?

Answer Details

The most appropriate option to fill the gap is "on." This is because the sentence structure suggests that Onimisi was proud of his fearlessness. The preposition "on" is commonly used to indicate a sense of pride or satisfaction with a particular attribute or achievement. In this case, the sentence suggests that Onimisi was proud of his fearlessness until something happened to challenge it.
