"Maintaining or improving information security while migrating to the cloud is more of a contractual than technical problem to solve." Which statement best shows why this is either true or false?

$$ a$.$ It is true. Cloud service models are constantly changing, and this means that the contracts, terms of service, or service level agreements are continually being updated. The underlying software technologies, however, don't change as much or as frequently.

$$ b$.$ It is false. The contractual side is similar to any other service provider relationship and is done once; the technical challenge of mastering a whole new set of features and capabilities is far larger and is always ongoing.

c$.$ It is false. The contractual agreements do change quite frequently as the underlying technologies, threats, and business case for both the cloud host and the customer change with time. However, even these changes cause less work, less frequently, for the administrative elements and more for the technical elements of the typical customer organization.

$$ d$.$ It is false. The contractual agreements do change quite frequently as the underlying technologies, threats, and business case for both the cloud host and the customer change with time. These changes cause about equal amounts of work on both administrative and technical elements of the customer organization.
