Let $P-i$ and $P_j$ 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 $p_i$ and $P_j$ which of the conditions are not true?

  1. $R(P_i) \cap W(P_j) = \Phi$
  2. $W(P_i) \cap R(P_j) = \Phi$
  3. $R(P_i) \cap R(P_j) = \Phi$
  4. $W(P_i) \cap W(P_j) = \Phi$

For a concurrent execution there should be no read-write ,write-write or write-read conflict.

as given option (a),(b) and (d) depicts the same which true option.

C represent the two simultaneous read operation of the process with no intersection variables which may not be case.

hence C is false.
