Which of the following is arranged in the increasing order of connotation ?

Connotation refers to the specific attributes or meaning associated with a term. As we move from general categories to specific ones, connotation increases while extension decreases. In biological classification, 'Animal' is a broad category with fewer defining attributes (low connotation), whereas 'Cow' is specific with many attributes (high connotation). Therefore, the correct arrangement from least to most connotation is from general to specific.
