Right option is (b) False

For explanation: In two-dimensional problems, the finite elements are simple geometric shapes. These shapes can be used to approximate a given domain as well as the solution over it. Because of double approximation the accuracy of solution depends on both the approximations and is errors in two approximations gets multiplied.
