Respectively they are 'K', 'N', 'O', 'T', ' DI'. Just like Offline Activation Request Information, it is also a JSON-style ASCII string. It is a Base64 string that represents 256-bytes-long data, while the 256-bytes-long data is the cipher text of the offline activation response information encrypted by Navicat Activation Private Key (so far, we don't know official activation private key). Respectively they are 'K', 'DI' and 'P', which represent snKey, checksum (related with your machine and OS), Platform (Appropriately speaking, it should be OS Type). It is just a JSON-style ASCII string which contains 3 items.

It is a Base64 string that represents 256-bytes-long data, while the 256-bytes-long data is the cipher text of the offline activation information encrypted by Navicat Activation Public Key. I would be very appreciated for your generous. If you have the corresponding private key, please tell me.

You can see it by a kind of software Resource Hacker. It is stored in navicat.exe as a kind of resource called RCData. It is a RSA-2048 public key that Navicat used to encrypt or decrypt offline activation information. This repository will tell you how Navicat offline activation works.
