Subflow inputs are crucial because they define the specific data that is passed to a subflow when it is executed. Each time a subflow is launched, it may require certain data or parameters to function correctly. By providing inputs, users ensure that the subflow has access to the necessary information it needs to carry out its tasks effectively. This can include variables like record IDs, user information, or any other specific data required for the subflow to operate as intended.

The other aspects mentioned in the options, such as actions performed, users who can execute the subflow, and conditions for running, pertain to different components of flow design but do not define the role of inputs specifically. Inputs are primarily about the data context in which the subflow operates, making option B the correct choice in this instance.
