The most accurate response that describes the effects of internal conflict on Rwanda is:
"Rwanda’s internal conflict led to years of trauma in the country. The years afterward were focused on reconciliation and recovery."
This response captures the profound impact of the conflict, especially the Rwandan Genocide in 1994, which resulted in significant loss of life and trauma. It also reflects the subsequent efforts made by Rwanda to heal and rebuild as a nation. The other statements may contain elements of truth but do not encapsulate the primary effects of the conflict as effectively.
