How does the Apostle Paul repurpose the concept of 'boasting' in his letters, particularly in 2 Corinthians, and what theological significance does this transformation hold?

A Paul completely rejects boasting as inherently sinful, emphasizing humility as the sole virtue. B Paul acknowledges boasting as a necessary evil for self-promotion in the competitive early church environment. C Paul transforms the concept of boasting, redirecting it from self-exaltation to boasting in Christ's weakness and God's grace, revealing a paradoxical strength in vulnerability. D Paul uses 'boasting' ironically, subtly mocking his opponents while maintaining a facade of humility.
