If the relation R : `A to B, ` where A={1,2,3} and B={1,3,5} is defined by `R= {(x,y):xlty,x in A,y in B},`then-A. `R={(1,3),(1,5),(2,3),(2,5),(3,5)}`B. `R={(1,1),(1,5),(2,3),(3,5)}`C. `R^(-1)={(3,1),(5,1),(3,2),(5,3)}`D. `R^(-1)={(1,1),(5,1),(3,2),(5,3)}`

Answer» Correct Answer - A
`x Ry iff x lt y we have
`1lt3,1lt5,2lt3,2lt 5,3lt 5`
`R= {(1,3),(1,5),(2,3),(2,5),(3,5)}`
