Validating the results of a program is important to a. correct runtime errors b. make sure the program solves the original problem c. create a model of the program d. correct syntax error

b. make sure the program solves the original problem

Explanation:

This is important so as to avoid logical errors. Logical errors unlike compiler or run time errors will not stop your code from compilling and executing but after your program compiles and runs, but does the wrong thing by given you unexpected results

This is the reason why validation of results after your code is completed is important in this way you are sure the program solves the original problem.
