Solution:A, B, E, P, R → A, E, F are selected together but in this case F is absent
D, P, R, C, Q → all other case are invalid so this seem to be valid,
B, P, R, C, T → B and T can not be selected together so, this case is invalid
A, B, C, E, F → C can be not selected with E and F so, this case is invalid
