In an opinion poll, the degree to which an opinion is subject to change is known as : B. stability

An opinion is categorized as stable if it's not easily change/swayed by a simple argument. People whose opinion has a high stability is usually really know their stuff about the subject, or simply a fanatic

When we're using opinion polls, the degree to which an opinion would and will be subject to change is known as it's stability - b. The more the opinion poll can be changed and is itself malleable, the less stable it is and vice versa.
