At an Electronic Data processing unit, five out of the eight program sets P, Q, R, S, T, U, V and W are to be operated daily. On any one day, except for the first day of a month, only three of the program sets must be the ones that were operated on the previous day. The program operating must also satisfy the following conditions:1. If program P is to be operated on a day, V can’t be operated on that day.2. If Q is to be operated on a day, T must be one of the programs to be operated after Q.3. If R is to be operated on a day, V must be one of the programs to be operated after R.4. The last program to be operated on any day must be either S or U.If the sequence of program sets operated on a day is P,Q,W,T,U, each of the following could be the next day’s program sets except.

• A. W, T, U, V, S
• B. W, T, S, P, U
• C. W, R, V, T, U
• D. Q, T, V, W, S
