Which of the following is a component included in the VSI?

The Visual Spatial Index (VSI) is one of the indices derived from the WISC-V, which assesses a child's ability to understand and manipulate visual information. The VSI incorporates various subtests that evaluate how well a child can process and interpret visual stimuli, as well as their ability to solve problems using visual-spatial reasoning.

In this context, each component mentioned corresponds to specific subtests that contribute to the VSI. For instance, "CD" refers to the Coding subtest, which measures a child's ability to quickly and accurately associate symbols with numbers, reflecting visual-perceptual processing. "MR" relates to the Matrix Reasoning subtest, assessing nonverbal reasoning and the ability to analyze visual patterns. "VP" stands for Visual Puzzles, which evaluates how well a child can visualize and manipulate parts to form a whole.

Since all these subtests are indeed part of the Visual Spatial Index, it is accurate to state that they collectively contribute to the VSI's assessment of visual-spatial abilities, thereby making "All of the above" the correct choice. This demonstrates how the components work together to provide a comprehensive evaluation of a child's visual-spatial intelligence.
