A Correct answer
Explanation

Drools is a business rule management system (BRMS) and rule engine released under the Apache License 2.0, which is a permissive free software license. The GNU Lesser General Public License (LGPL) is a different license used by some Java libraries but not Drools. The 'All of the above' option is incorrect because only the Apache License applies.
