a. womenís roles in times of combat.
b. the causes and effects of world wars.
c. the violence directed at noncombatants.
d. bringing war criminals to justice.

C). The violence directed at noncombatants.

Explanation:

War literature is chiefly inclined towards depicting the action that took place in the battleground. Such literature is developed entirely around the war scenario where characters are obsessed with making arrangements for the battle or bearing the aftermath of the war or trying to recuperate or retrieve from the after-effects of the war. War literature is centrally aiming to depict the violence and bloodshed caused by the war and repercussions associated with it(internal(mental) and external(physical) struggle).

As per the question, the war literature of twentieth-century American writers like Elie Wiesel paid attention to 'the violence directed at non-combatants' as the civilians suffered extreme brutality and violence which was the outcome of the battle. Thus, option C is the correct answer as the writers reflected the aftermath of war by depicting the 'violence directed at them'.
