The most relevant consequence of the Moroccan Crisis was:
3) Increased tensions between France and Germany.
The Moroccan Crisis (particularly the first crisis in 1905 and the second in 1911) heightened tensions between these two nations, as Germany sought to challenge French influence in Morocco, leading to diplomatic confrontations. While there were broader implications affecting relations with Britain and the naval arms race, the direct result of the crisis was primarily the escalation of hostilities and suspicions between France and Germany.
So, although 2) might have some relevance related to the broader naval context, 3) is the most straightforward consequence of the Moroccan Crisis itself.
The other options, such as 1) and 4), do not accurately represent the main outcomes of the crisis. The Berlin Conference referred to an earlier event (1884-1885) focused on the partition of Africa, and while the crisis affected great power relations, it did not lead to a decision to call another Berlin Conference.
