B. The ships were at the mercy of the weather.

The main reason why the transatlantic journey of the Middle Passage took longer than the expected time in some instances was because the ships were at the mercy of the weather.

In those days weather forecasting was not advanced as it is today. It was thus difficult to predict the occurrence of bad weather such as storms and hurricanes which would in turn slow down the journey thus taking longer than expected.
