Plasmodium vivax/ovale have dormant stages where their hypnozoites can stay latent in hepatocytes and trigger malaria well after the initial infection. The only malarial drug that covers against this is primaquine. The answer choice is just worded funny - "exoerythrocytic malarial tissue stages" basically is the stage where they are in the liver/not in RBC, and chloroquine won't work for those.
