Step-by-step explanation:
The factor that most contributes to intergovernmental organizations' inability to successfully stop ethnic cleansing and genocide is option B - Intergovernmental organizations often find it difficult to determine whether abuses fit the strict definition of genocide that would make intervention legal.
GENOCIDE RECOGNITION: Intergovernmental organizations such as the United Nations (UN) use a specific legal definition of genocide to determine whether intervention is warranted. This definition includes acts such as killing, causing serious bodily or mental harm, or deliberately inflicting conditions of life on a group with the intent to destroy them. However, determining whether abuses meet this definition can be a complex process, and intergovernmental organizations may struggle to gather accurate and timely information.
EXAMPLES: The situation in Darfur, Sudan, highlighted the challenges faced by intergovernmental organizations in recognizing and responding to genocide. Despite mounting evidence of mass killings and widespread atrocities, the UN Security Council was divided about whether to label the situation as genocide.
