Which of the following is the Amazon Resource Name (ARN) condition operator that can be used
within an Identity and Access Management (IAM) policy to check the case-insensitive matching of
the ARN?

A.
ArnCheck

B.
ArnMatch

C.
ArnCase

D.
ArnLike

Explanation:
Amazon Resource Name (ARN) condition operators let you construct Condition elements that
restrict access based on comparing a key to an ARN. ArnLike, for instance, is a case-insensitive
matching of the ARN. Each of the six colon-delimited components of the ARN is checked
separately and each can include a multi-character match wildcard (*) or a single-character match
wildcard (?).
