Invoking trigger when an answer is marked as Best Answer in Chatter

I am trying to invoke a trigger when an answer is marked as Best Answer in Chatter (not in Community). I tried a trigger on FeedItem and FeedComment objects, but the triggers were not invoked when I mark an answer as a Best Answer. Can someone help?

I think you have are using chatter answers .. so the trigger on the FeedItem and FeedComment  wnt work .. 

you need to use the Question  objects 

You have to BestReplyId  and BestReplySelectedById based on the requirement 


https://developer.salesforce.com/docs/atlas.en-us.object_reference.meta/api/sforce_api_objects_question.htm?search_text=Question
  
trigger BestAnswerTrigger on Question (before update) {
    for (Question q: Trigger.new) {
        if (q.BestReplyId!=null) {
           // Logic will go here 
        }
    }
}

It is a very new org created less than 6 months back and I am sure its Chatter Questions (not Chatter Answers). I tried creating a trigger on Question object, but I get an error Invalid type: Schema.Question while trying to save.
