Solution

The correct option is C coli
EcoRI is a restriction endonuclease enzyme where 'Eco' stands for the genus and species name of the organism it is isolated from i.e Escherichia coli. The R represents the particular strain, in this case RY13. The last part of its name, the ‘I’, represents the order of discovery.
