The requirement is to cascade only the project start date to its tasks, while leaving the finish date unaffected by project-level changes. In the project template's planning options, the "Cascade Date Changes" setting controls this behavior. Selecting "Cascade change to the start date" ensures that any modification to the project's start date will automatically adjust the start dates of all its tasks, but changes to the project's finish date will not be cascaded. This provides the specific control requested by the customer.

B. This option would prevent any date changes at the project level from cascading to tasks, which contradicts the requirement to cascade the start date.

C. This option would cascade only the finish date, which is the opposite of the customer's requirement.

D. This option would cascade both start and finish date changes, which is explicitly not what the customer wants for the finish date.
