Here are the essential concepts you must grasp in order to answer the question correctly.
Vector Components
Vector components are the projections of a vector along the axes of a coordinate system. In a two-dimensional space, any vector can be broken down into its x-component and y-component, which represent the vector's influence in the horizontal and vertical directions, respectively.

Unit Vectors
Unit vectors are vectors with a magnitude of one, used to indicate direction along the axes in a coordinate system. In Cartesian coordinates, the unit vectors i and j represent the x-axis and y-axis directions, respectively, allowing vectors to be expressed in terms of these components.

Vector Notation
Vector notation is a mathematical representation of vectors using symbols and numbers. In physics, vectors are often expressed in terms of their components using unit vectors, such as A = 11.2j - 9.91i, where the coefficients of i and j indicate the magnitude of the vector's components along the x and y axes.
