In EcoRI, 'co' stands for coli (species of bacteria, from where it is obtained)
EcoRI is an endonuclease enzyme isolated from strains of E. coli, and is part of the restriction modification system. In molecular biology, it is used as a restriction enzyme. It creates 4 nucleotide sticky ends with 5' end overhangs of AATT.
So, the correct answer is option A.
