A wouldn't help, it just bottles up their feelings, even more, hurting them in the end worse. Medication can't always be the answer, and you can help with everyday errands, and refer them to a hospice depending on how much this grief is deteriorating their mental health. Based off of where they are mentally, all of these would be a good idea, except A. Help them talk about their stresses but only if they are comfortable with it.
I don't know if this is for homework, or for personal reasons. This answer only really helps with personal reasons.
