The correct option is B Competition
Connel's experiment explained that two species of barnacles live in a stratified distribution in the intertidal region along the Scottish coast. Balanus is observed to be most concentrated in the lower intertidal area whereas Chthamalus is observed to be most concentrated in the upper intertidal area.
In experiment 1, Connell removed Chthamalus from the upper area, and no Balanus replaced it. This showed that balanus could not survive in an area with low tides.
In experiment 2, Connell removed Balanus from the lower area and Chthamalus replaced it. This showed that balanus was a more successful competitor in the lower intertidal zone.
This proves that competition occurs in nature between Balanus and Chthamalus.
