Answer:
Step-by-step explanation:
So, if we can define each word it will make it easier. Desolate refers to being in a state of emptiness. Rigorous refers to or could be being accurate (cross that one out). Omen is a good or bad event. Devoid is lacking something (lacking emotion or lacking a voice). So my answer is desolate because it involves nothing, or just being empty (not necessary).
