Correct Answer: (3) Organism X=unicellular; organism Y=simple multicellular

According to most theories on evolution, the initial organisms of the Earth were simple and then evolved to more complex organisms in order to cope up with the changing environments. Thus, all the other options are incorrect, except for option (3), wherein organism X is a unicellular organism that may be evolved into simple multicellular organism like organism Y.
