Birth records of 4 babies were mixed up in a hospital. The ABO blood groups of the four babies were known to be $\mathrm{A}, \mathrm{B}, \mathrm{AB}$ and O . To determine their respective parents, blood groups of all parents, except the father of baby III were tested. Choose the correct statements:
$\begin{array}{|c|c|c|}\hline & \text{Blood Type} \\ \hline \text{Parents I} & \text{father} & \text{AB} \\ 2 - 3 & \text{mother} & \text{O} \\ \hline \text{Parents II} & \text{father} & \text{A} \\ 2 - 3 & \text{mother} & \text{O} \\ \hline \text{Parents III} & \text{father} & \text{Unknown} \\ 2 - 3 & \text{mother} & \text{A} \\ \hline \text{Parents IV} & \text{father} & \text{O} \\ 2 - 3 & \text{mother} & \text{O} \\ \hline\end{array}$
