Final answer:
The phrase 'ever changing' best aligns with the term 'dynamic,' indicating continuous change or development, especially when referring to characters in literature. The correct answer is option A, 'dynamic.'
Step-by-step explanation:
The phrase 'ever changing' suggests something that is continuously in a state of change or flux. In literature, characters can be broadly categorized into two types: those that remain the same, known as static or flat characters, and those that undergo development or change, known as dynamic or round characters. Therefore, the best answer to complete the sentence 'Ever changing ____________' would be option A dynamic. This reflects the idea that something dynamic is constantly evolving or shifting, much like a character in a story who experiences significant growth or change throughout the narrative. In contrast, options B 'constant' and C 'stock character' imply little to no change, whereas option D 'fluid' might suggest variability but lacks the connotation of progressive change associated with 'dynamic'.
