   <i class="bi bi-check-circle" role="img" aria-label="Success"></i> uses role="img" and aria-label="Success", making it accessible. <i class="bi bi-check-circle" aria-hidden="true"></i> <span class="visually-hidden">Success</span> hides the icon from screen readers, B puts text inside icon tag (not semantic), D lacks role attribute.

3. Final Answer:

   <i class="bi bi-check-circle" role="img" aria-label="Success"></i> -> Option A

4. Quick Check:

   Use role="img" + aria-label for accessible icons = C [OK]
