The correct option is (c) Larger and competitively superior barnacle Balanus
 
The explanation: The larger and competitively superior barnacle BalanusI dominates the rocky coasts of Scotland. Due to this the smaller barnacle Chathamalus is excluded from that zone. It is an example of ‘competitive release’ which was shown by Connell’s elegant field experiments.
