Comparsion of CouchDB vs MongoDB Regarding CAP(Consistancy,Availability,Partition) Principle

I have been confused by different answers of couchDB and MongoDB (e.g http://blog.scottlogic.com/2014/08/04/mongodb-vs-couchdb.html this blog tells that MongoDB is CP and CouchDB is AP) ,however this answer When to use CouchDB over MongoDB and vice versa tells that Mongo DB is AP and CouchDB is CP)

can Anyone please solve my confusion?

From http://guide.couchdb.org/draft/consistency.html

Showing where CouchDB lay on the CAP triangle

I think the confusion might come from the fact that you can talk about couchDB as a single node and as couchDB as a cluster of nodes. When you're working with couchDB as a single node it will be consistent, but that is true for MongoDB as well. But when you work with couchDB as a cluster consistency is the first to go, you might get different versions of the document depending on which node you request it from.
