The correct answer to this open question is the following.

Although there are no options attached, we can say the following.

What Francis, Elizabeth's advisor, confessed to Elizabeth that he had intercepted right before England was invaded by Spain, was the plot that was planned to assassinate Queen Elizabeth and put Mary of Scotland on the throne of Britain.

Let's remember that Elizabeth was a protestant Queen and Mary was a Scottish Catholic Queen. Of course, this was the short-range goal of the plot. What really was at the core of the plot was the invasion of the Spanish Navy over England, supported by the Holy League of France and the King of Spain, Philip II. These two urged to reinstall the Catholic religion in the British territories.
