Right answer is (c) increase in calcium ions

To explain I would say: When the antigen-presenting cells – dendritic cells display fragments of antigens on their surface in the lymph nodes, the binding with a particular T-cell receptor occurs that leads to activation of the latter. The activation is associated with a transient increase in cytosolic calcium concentration.
