The correct choice is Dependencies section. CloudFormation does not support a top level Dependencies section and resource ordering or relationships are expressed using attributes such as DependsOn and by referencing resources inside the Resources section.

CloudFormation templates follow a defined anatomy and do not include arbitrary top level sections. The template expresses dependency relationships at the resource level so you use attributes and intrinsic functions rather than a separate Dependencies section to control creation order and references.

Parameters section is valid and lets you pass values into a stack at creation or update time so you can parameterize templates for reuse.

Resources section is valid and it is the only required top level section because it contains the declarations of the AWS resources that the stack manages.

Conditions section is valid and it lets you conditionally create resources or set property values based on evaluated expressions.
