Final answer:
The English Bill of Rights prohibited an English monarch from being Catholic or marrying a Catholic to maintain a Protestant monarchy and prevent Catholic influence.
Step-by-step explanation:
According to the English Bill of Rights, an English monarch cannot be a Catholic nor can they marry a Catholic. This rule was established following the Glorious Revolution, when Parliament sought to ensure that the monarch would uphold Protestant values and not be influenced by Catholicism, which had previously been associated with absolutist tendencies in monarchy.
The English Bill of Rights, which was passed by Parliament in 1689, specified that the kings of England should be Protestants and prohibited them from marrying Catholics. This was done to ensure the protection of the Protestant faith and to prevent any influence from the Catholic Church on the monarchy. Therefore, according to the English Bill of Rights, an English monarch cannot be a Catholic or marry a Catholic.
The Triennial Act was separate legislation that mandated Parliament must meet at least once every three years, even if it had not been called by the Crown (option c).
