Answer options:

A.Metadata
B.Parameters
C.Mappings
D.Resources

Answer: B
Option A is incorrect because the metadata section is used to provide information about the template.
Option B is CORRECT because the parameters section is used to pass values to the template during CloudFormation runtime.
Option C is incorrect because the mappings section is used to define key and matching value mapping pairs.
Option D is incorrect because the resources section is used to specify resources that should be provisioned by the template.
