Which of the following is an IL-6 inhibitor?

Explanation:
Blocking IL-6 signaling reduces inflammatory responses driven by this cytokine. Tocilizumab is a monoclonal antibody that binds the IL-6 receptor, preventing IL-6 from engaging its receptor on target cells. This stops the gp130/JAK-STAT signaling cascade and lowers downstream effects such as hepatic production of acute-phase proteins (like CRP) and fever. That mechanism makes it an IL-6 inhibitor, useful in conditions like rheumatoid arthritis, giant cell arteritis, and cytokine-release syndrome. Anakinra blocks the IL-1 receptor, Etanercept neutralizes TNF-alpha, and Rituximab targets CD20 on B cells, so they are not IL-6 inhibitors.
