Correct answer: D — Use a monoclonal TNF inhibitor such as adalimumab or infliximab
Explanation lettering: D = shown as A · E = shown as B · B = shown as C · C = shown as D · A = shown as E
C is correct. A monoclonal TNF antibody can treat axial SpA, Crohn disease and uveitis. A is unsuitable because etanercept lacks reliable IBD efficacy. B is unsuitable because IL-17 inhibition can aggravate active IBD. D is wrong because apremilast is not an established treatment for axial disease or Crohn disease. E treats Crohn disease but has not demonstrated the necessary axial efficacy. Gastroenterology and ophthalmology input still informs product choice.
