A BizTalk Server 2010 orchestration calls a Business Rules Engine policy. This policy evaluates test scores to determine whether a candidate passes or fails. The BizTalk solution and the policy are deployed. Business users have decided that the value of a passing score should be raised from 60% to 70%. You need to adjust the policy to reflect the modified rule parameter. What should you do?

A.
Open the policy in the Business Rules Composer. Create a new version of the policy and edit this version to reflect the changed parameter. Then deploy the new version.

B.
Open the policy in the Business Rules Composer. Create a new version of the policy and edit this version to reflect the changed parameter. Then publish the new version.

C.
Create a new vocabulary in the Business Rules Composer. Add the new parameter to this vocabulary and then publish the vocabulary.

D.
Open the policy in the Business Rules Composer and create a different policy with a new name. Then copy the currently deployed version to the new policy and modify to reflect the changed parameter.
Deploy the new policy.
