If the program sets R and W are to be operated on the first day, which of the following could be the other programs on that day ?
Answer: D
Since R is operated, so V must also be operated.
Also, S or U is to be taken at the end.
So, the possible combinations are Q, S, V and T, S, V.
Now, Q must have T as one of the programs after it, which is not possible. So, Q, S, V is incorrect
