Answer:
The correct answer is B. They are a collection of minerals or a body of glass.
Explanation:
The study of rocks needs the observation of their characteristics; its characteristics depend on the properties of the minerals that compose it, its relative amounts and the way in which these were joined to originate the rock. Texture is the external appearance of any rock. It depends on the shape, size and internal arrangement of mineral crystals. Each of these characteristics maintains its specific properties (chemical and physical) in the rock as a whole.
In a rock we can distinguish two types of minerals:
Essential minerals. They are the ones that constitute the nature of the rock and give it its characteristics and properties for being in greater proportion. The lack of one of them would result in the formation of a different rock with different properties.
Accessory minerals These are minerals that appear occasionally in very low proportions within the typical composition of a particular rock. Its presence does not alter the basic characteristics of the rock.

Answer:
A. The reader learns that she is confident and composed which makes her appear credible.
Explanation:
Saki's short story "The Open Window" is about a character named Framton Nuttel who had gone to his new neighbor's house to be introduced. And while waiting for the lady of the house, he was told a rather ghastly story by the niece Vera, which was in fact, just a lie.
Through her narration of how her aunt keeps the window open in anticipation of the arrival of her husband and brothers from their hunting, Vera managed to 'horrify' Framton. So, when the hunting party arrived, Framton dashed out of the house, which Mrs. Sappleton admits <em>"One would think he had seen a ghost"</em>. And Vera's declaration of how it must have been the spaniel that led Mr. Framton rushing out of the house shows how self-possessed she is and also contributes to the reader's understanding of her character. She finds joy in the scene and seems to be enjoying it. And <u>her confident and composed nature at the scene shows her self-possessed nature.</u>
Thus, the correct answer is option A.
