Answer the following questions based on the information given below:
A leading socialite decided to organize a dinner and invited a few of her friends. Only the host and hostess were sitting at the opposite ends of a rectangular table with three people on each side. The pre-requisite of the sitting arrangement was that each person must be seated such that at least on one side he/she has a person of the opposite sex. Maqbool is opposite to Sobha, who is not the hostess. Ratan has a woman on his right and is sitting opposite to the woman. Manisha is sitting to the hostess’s right, next to Dhirubhai. One person is seated between Madhuri and Urmila, who is not the hostess. The men were Maqbool, Ratan, Dhirubhai and Jackie, while the woman were Madhuri, Urmila, Sobha and Manisha.
If Ratan would have exchanged seats with a person four places to his left, which of the following would have been true after the exchange?
I. No person of the opposite sex was seated between two persons of the same sex (e.g., No man was seated between two women).
II. One side of the table consisted entirely of persons of the same sex.
III. Either the host or the hostess changed their seat.
