Let Pᵢ and Pⱼ be two processes, R be the set of variables read from memory, and W be the set of variables written to memory. For the concurrent execution of two processes Pᵢ and Pⱼ which of the following conditions is not true?
  1. AR(Pᵢ) ∩ W(Pⱼ) = Φ
  2. BW(Pᵢ) ∩ R(Pⱼ) = Φ
  3. CR(Pᵢ) ∩R(Pⱼ) = Φ
  4. DW(Pᵢ) ∩W(Pⱼ) = Φ
