The correct answer is A) reading the Bible.
Puritans were individuals who wanted to "purify" (aka fix) the Church of England during the 17th century. Due to widespread corruption, the Church of England was viewed negatively by many citizens. To fix this belief and view, Puritans who traveled to North America to establish lives focused on returning to Biblical teachings in order to guide their actions. This focus on the Bible and its teachings allowed citizens to stray away from the corruption of church officials. Citizens would act according to Biblical teachings, not the wishes or orderes of corrupt clergymen.
