In N, R = {(x, y): y = x + 5 and x < 4} is
AReflexive and symmetric but not transitive
BTransitive but neither reflexive nor symmetric
CSymmetric and transitive but not reflexive
DAn equivalence relation holding on N
Answer & Solution
Correct answer: B. Transitive but neither reflexive nor symmetric
R contains only (1,6), (2,7), (3,8); it lacks (x, x) and reverses, and no chain (a, b), (b, c) exists, so transitivity holds vacuously.
