Final answer:
John Lennon did not claim any specific song broke up the Beatles. The breakup was due to a combination of personal, financial, and artistic differences. 'The Ballad of John and Yoko' recorded by only John and Paul caused some friction but is not the reason for the breakup.
Step-by-step explanation:
John Lennon is often quoted regarding various reasons why the Beatles broke up, one of the greatest bands in the history of music. Despite numerous speculations and comments, there is no specific song that John attributed as being the reason for the breakup. However, looking at the options provided, it's clear that none of those songs are directly associated with the break-up according to widespread sources. John and other members have cited numerous personal, financial, and artistic differences as contributing factors to the break-up.
The closest connection to a song potentially contributing to tensions within the band would be 'The Ballad of John and Yoko,' which chronicled John and Yoko Ono's wedding and honeymoon. While not the cause, it did create some friction as it was recorded by just John and Paul due to the absence of George and Ringo at that time.
