What is the domain of the relation described below:

There are 6 points on a coordinate plane. The points are (negative 5, 0), (negative 4, 1), (negative 3, 4), (1, negative 2), (2, 4), (5, negative 3).

A domain: {–5, –4, –3, –2, 0, 1, 2, 3, 4, 5}
B domain: {–3, –2, 0, 1, 4}
C domain: {–5, –4, –3, 1, 2, 5}
D domain: {(–5, 0), (–4, 1), (–3, 4), (1, –2), (2, 4), (5, –3)}

(4^(1/4)(x^(2/3)y^(-1/3))^(-2))/4^(-1/4)(8xy)^(2/3)
