Question

The relation R defined in N as a blank R blank b ⟺ b is divisible by a is

  1. Reflexive but not symmetric  
  2. Symmetric but not transitive  
  3. Symmetric and transitive  
  4. None of these  

The correct answer is: Reflexive but not symmetric


    For any a element of N comma we have a vertical line a
    Therefore R is reflexive
    R is not symmetric, because a blank R blank b does not imply that b blank R blank a
