Wow! 95 - God bless her!
Now, as far as the policy - because of her age, I would say either option 2 or 3, leaning more towards 2 - no more premiums and have the coverage. Based on the way you listed them, I'm understanding that $55k in option 2 is not set to any daily limit, just that it's $55k maximum payout. I think that is better than the options 1 and 4 which have daily caps. If the time comes when you need it, you'd be able to go for better quality/comfort for $100 or more a day if you like.
