B Correct answer
Explanation

From 'All industrious boys have red hair' and 'Some industrious boys are boarders', we know that those industrious boys who are boarders also have red hair. Therefore, some boarders have red hair. Option A is incorrect because we only know about the industrious boys who are boarders, not ALL boarders - there could be boarders who are not industrious and don't have red hair.
