Universal Container’s Sales VP requested the Salesforce Admin to enable opportunity splits. What happens when the opportunity splits are enabled?

Answer options:

A.Credit can be split for an opportunity among opportunity team
B.Users below opportunity owner have the privilege to split the credit among the opportunity team
C.Users with the same opportunity owner profile has the privilege to split the credit among the opportunity team
D.A validation rule is created to arrange the credit split

Correct Answer: A 
Once the opportunity split is enabled, the credit can be split for the opportunity among the opportunity team. 
Option B & C are incorrect because only the opportunity owner and users above the owner in the role hierarchy can add or adjust the opportunity splits. 
Option D is incorrect because validation rule is used to verify that the data entered by the users meet the standards you have specified before they save it.
