Let A = {-42, -7, -6, -2, 1, 10, 11, 29} be a set.
Define a binary relation R on A as follows:
For all r, y € A, zRy if and only if x = y (mod 9).
Given that R is an equivalence relation on A, which one of the following sets P is a partition
of A into equivalence classes of R?
Choose the correct answer
= {{-42}, {-6}, {-7,11}, {29, -2}, {1}, {10}}
A. P =
B. P ={{-42, -7, -6, -2, 1, 10, 11,29}}
C. P ={{-42, -7,-6}, {-2,1}, {10, 11,29}}
D. P= = {{-42,-6}, {-7,11,29},{-2}, {1,10}}
E. P ={{-42, -6, -7), (11,29},{-2}, {1,10}}
F. P ={{-42,-6}, {11,29}, {-7, -2}, {1, 10}}
