The correct option is option A "She puts the needs of others before her own".
In this short and masterfully written excerpt, the author does an excellent job introducing the depths of the character of Ruth by giving away just a few crucial details.
Ruth checks up on her husband who is getting up, without calling attention to herself. Immediately after, she returns to the kitchen, wiping her face and fixing her hair in an attempt to hide her exhaustion and go on with her duties.
This description paints a clear picture of a woman that is putting the needs of others before her own. That is the strongest sense we take away from the excerpt.
Hope this helps!
