Consider the following parallel pseudo-code with future tasks. Select the statment below which must be true for this code snippet: - - - - - - - - - - - - - - - - - - - - - - - - - - - - finish { future A = future { $1; return 1;} ; future B = future { $2; int a = A.get(); 33; return 3;} ; future C = future { int a = A.get(); S4; int b = B.get(); S5 ; return 5;} ; - ----------------------------------- O A. S1 can run in parallel with S3. O B.S2 can run in parallel with S5. O C. S1, S2, and S4 can all run in parallel with each other O D. S2 can run in parallel with S4. O E. S4 can run in parallel with S5
