The correct answer is: A. a little.
The word “little” is used to describe something that is small in amount or degree. In this case, it is being used to describe the amount of hope that there is for the person’s survival. The word “few” is also used to describe something that is small in amount or degree, but it is typically used to describe a number of things, rather than a degree of something. In this case, it would not make sense to say that there are “few hopes” for the person’s survival, because hope is not something that can be counted. The words “a little” and “little” are both singular forms, but they have different meanings. “A little” is used to describe something that is small in amount or degree, but it is still significant. In this case, it is being used to describe the amount of hope that there is for the person’s survival. “Little” is used to describe something that is small in amount or degree, and it is not significant. In this case, it would not make sense to say that there is “little hope” for the person’s survival, because that would mean that there is no hope at all.
