Final answer:
A reagent lease/rental agreement allows for greater flexibility in reagent selection, allowing researchers to adapt and experiment with different reagents without the need to purchase them outright.
Option B.
Step-by-step explanation:
An advantage of reagent lease/rental agreement is greater flexibility in reagent selection.
When leasing or renting reagents, you have the option to choose different reagents based on your specific needs or experiments.
This allows you to adapt your reagent selection as your research evolves and new reagents become available.
It also provides an opportunity to test and experiment with a variety of reagents without the need to purchase them outright.
