In FEM, what is the name of the element specified by a polynomial of order two or more?

(a) Nonlinear element

(b) Higher-order element

(c) Linear element

(d) Master element

I got this question in an internship interview.

My query is from Library of Elements and Interpolation Functions in division Interpolation Functions, Numerical Integration and Modelling Considerations of Finite Element Method

The correct choice is (b) Higher-order element

To explain: Simplex and linear elements contain nodes only at endpoints but not at the interior. They have linear polynomials as interpolation functions. Higher-order elements can be created easily from simplex elements by adding additional intermediate nodes to each element. They are also called complex elements.
