Explanation

Statements A, B, and C correctly describe the Lock and Key Model: enzymes have specific substrates, and their active sites are considered rigid and unchanging throughout the reaction. However, statement D is incorrect because the Lock and Key Model does not explain the mechanism of every chemical reaction; it specifically describes enzyme-substrate interactions.
