Answer: (A)
Solution
Inner transition elements are the f-block elements, i.e. the lanthanoids (Ce to Lu, filling 4f) and the actinoids (Th to Lr, with Ac as the prototype element, filling 5f). Ho (Z = 67) is a lanthanoid, Lu (Z = 71) is the last lanthanoid (the 14th element after La/Ce) and Ac (Z = 89) is
