Hello dear,

◆ Answer - (c)

In EcoRI, the R is derived from name of strain.

● Explanation -

• Restriction endonucleases are named according to specific nomenclature.
• First 3 letters indicate genus & species of the bacterium from which it's derived, next letter indicates the strain of the organism & lastly comes the order in which the enzyme was discovered.
• In EcoRI, Eco stands for E.coli, R stands for strain Rd & I means it's 1st enzyme to be discovered in that series.
