Solution :
The intermediate state and the transition state are used to describe the chemical species that is along the reaction pathway.
Therefore, the phrase of the term that it describes each of the terms, intermediate, transition state analogue and transition state are as follows :
a. Compound which is designed to mimic the structure of the transition state
-- transition state analogue
b. Containing partially formed as well as partially broken bonds.
-- transition state
d. Often serves as the potent enzyme inhibitor
-- transition state analogue
