Final answer:
The correct option for the multivariable critical point calculator is Option A) MultiCritPointCalc.
Step-by-step explanation:
The correct option for the multivariable critical point calculator is Option A) MultiCritPointCalc. This calculator is designed to help find the critical points of a multivariable function, which are the points where the gradient is zero or undefined. By inputting the function into the calculator, it will provide the critical points along with other useful information such as the Hessian matrix and the type of critical point (maximum, minimum, or saddle point).
