Correct answer: B — Full blood count and liver function tests

Azathioprine can cause bone marrow suppression and hepatotoxicity, requiring regular monitoring. In this vignette, "Full blood count and liver function tests" is the safest single best answer. The other options are less appropriate because they miss the key clinical risk, conflict with UK medicines guidance, or delay needed review.
