C might be correct: p115 - If current polices are insufficient to meet the business need, the business analyst identifies the changes necessary for the desired future state.
Policies are a common source of constraints on a solution or on the solution
space. Business policies may mandate what solutions can be implemented given
certain levels of approval, the process for obtaining approval, and the necessary
criteria a proposed solution must meet in order to receive funding. In some
instances, a change to an existing policy may open up alternative solutions that
would not otherwise be considered.
