Explanation
According to Oracle documentation3, Oracle's recommended method to define a chart of accounts that includes an intercompany segment when your customer plans to use segment value security rules for the Company segment is to share the same value set for the company and intercompany segments. Sharing the same value set enables you to use segment value security rules for both segments and ensures that the values in both segments are consistent. Therefore, option B is correct. Option A is incorrect because defining the intercompany segment with a default value does not enable segment value security rules for the intercompany segment. Option C is incorrect because defining the company segment and assigning both the primary balancing segment and intercompany segment labels does not enable segment value security rules for the intercompany segment. Option D is incorrect because creating two different value sets for the company and intercompany segments does not ensure that the values in both segments are consistent.
