In investigating the deportation and mass killing of Armenians during the Armenian Genocide, the following statement is true:
Deported Armenians experienced starvation, violence, and disease.
This encompasses the harsh realities faced by Armenians during their deportation, where many suffered from these dire conditions. The other statements either misrepresent the chronology of events, the conditions of deportation, or the weight of evidence regarding the nature of the actions taken against the Armenian population.
