The correct answer is co-adaptation.
Co-adaptation in biology refers to the procedure by which two or more species, phenotypic traits or genes go through adaptation as a group or pair. This takes place when two or more associating features go through natural selection together in response to the similar selective pressure or when selective pressures change one feature and simultaneously changes the interactive feature. These associating features are only beneficial when together, in certain cases resulting in increased interdependence.
