Final answer:
Option A is answer. The group of students at Oxford known for pursuing holiness was the Holy Club, founded by Charles Wesley.
Step-by-step explanation:
The group of earnest young men from Oxford University who aimed to 'follow after' holiness were known as the Holy Club. Founded in 1729 by Charles Wesley, this group of devout students was meticulous in their religious devotions, which eventually earned them the nickname Methodists. This term later came to identify the Protestant denomination they helped to establish. The Wesley brothers were inspired by their encounter with the writing of Martin Luther, which led to their spiritual conversion. They emphasized the importance of a personal, emotional relationship with God and engaged extensively in missionary work and public service.
As Anglicans, the Wesleys found inspiration in the writings of Martin Luther, particularly his concept of Justification by Faith. Their transformative experiences in 1738 led them to adopt a more evangelical approach that influenced their preaching and spiritual practice, which would eventually expand to the American colonies.
