Final answer:
The Matrix calculator (option B) can be used for solving systems of linear equations in matrix form.
Step-by-step explanation:
The calculator that can be used for solving systems of linear equations in matrix form is a Matrix calculator (option B). Matrix calculators are specifically designed to perform matrix operations, including solving systems of linear equations in matrix form. These calculators allow you to input the coefficient matrix and the constant vector and then perform operations like row operations, finding determinants, and solving the system using methods like Gaussian elimination or Cramer's rule.
