Explanation:
Hail Stones:- Hail is a form of solid precipitation. It is distinct from ice pellets, though the two are often confused. It consists of balls or irregular lumps of ice, each of which is called a hailstone.
Arrows:- An arrow is a fin-stabilized projectile that is launched via a bow, and usually consists of a long straight stiff shaft with stabilizers called fletchings, as well as a weighty (and usually sharp and pointed) arrowhead attached to the front end, and a slot at the rear end called the nock for engaging the bowstring.
Based on my prior knowledge of the word I would say C (unoriginal) is a pretty safe choice.
Clustering is an important prewriting technique much like brainstorming and allows the writer to: (D) generate ideas and see connections between them. The trick is to write down whatever words related to a specific word or phrase comes to a writer's head. It is then key to draw associations between words to determine topic of an essay.
