If \( R \) be a relation \( \) from \( A=\{1,2,3,4\} \) to \( B=\{1,3,5\} \) i.e., \( (a, b) \in R \) iff \( ab \), then \( \operatorname{RoR}^{-1} \) is
(a) \( \{(1,3),(1,5),(2,3),(2,5),(3,5),(4,5)\} \)
(b) \( \{(3,1),(5,1),(3,2),(5,2),(5,3),(5,4)\} \)
(c) \( \{(3,3),(3,5),(5,3),(5,5)\} \)
(d) \( \{(3,3),(3,4),(4,5)\} \)
