Answer 1

I managed to fix the Issue yesterday. While investigating I noticed the my domain name was assigned 4 name servers. The two nameservers shown on settings tab were different from the two nameservers shown on DNS Zone file tab due to which Google blogger was unable to verify domain ownership [Note: I have attached the screenshot of the issue for users reference]. After replacing the two nameservers on "settings" tab with the two nameservers on "DNS Zone File" tab the issue got fixed.

Godaddy Setting Tab Section:

Godaddy DNS Zone File Section:

Hope this information might help others!
