An investigation into the battle of lepanto reveals that which of the following was a factor in the battles outcome?

The correct answer is **B. The weakness of the Ottoman navy**.

The Battle of Lepanto, fought on October 7, 1571, saw a coalition of Christian states, known as the Holy League, facing the Ottoman Empire's navy. The Ottomans were ultimately defeated, and one of the key factors in this outcome was the relative weakness and disorganization of their naval forces compared to the well-coordinated fleet of the Holy League. While the Ottomans had some modern artillery and organizational skills, their naval weakness played a more significant role in the defeat during this battle.
