A particle of unit mass is moving along the x-axis under the influence of a force and its total energy is conserved. Four possible forms of the potential energy of the particle are given in Column I (a and U0 are constants). Match the potential energies in Column I to the corresponding statement(s) in Column II: 

- A(A)→(P), (Q), (R); (B)→(Q), (S); (C)→(P), (Q), (R), (S); (D)→(P), (R), (T)
- B(A)→(P), (Q), (R), (T); (B)→(Q), (S); (C)→(P), (Q), (R), (S); (D)→(P), (R), (T)
- C(A)→(P), (Q), (R), (T); (B)→(Q); (C)→(P), (Q), (R), (S); (D)→(P), (R), (T)
- D(A)→(P), (Q), (R), (T); (B)→(Q), (S); (C)→(P), (Q), (R), (S); (D)→(P), (R)
