Final answer:
Jonathan Swift's early ambition was the Church, and he changed his career path due to a lack of support, eventually becoming Dean of St. Patrick's Cathedral in Dublin and an influential satirist. Option b is correct.
Step-by-step explanation:
In Jonathan Swift's Gulliver's Travels, the early ambition of the author was b) Church, due to a lack of support. Jonathan Swift initially pursued a career in the church and eventually became the Dean of St. Patrick's Cathedral in Dublin.
Swift's shift in career path was influenced by the political and religious complexities of the time, which impacted his ability to advance within the church hierarchy.
Despite the challenges, Swift's role in the church did provide him with a platform to express his political views and engage in the social and political issues of his day, often through satire and written works like Gulliver's Travels.
