Solution
The correct option is A Titanium
Titanium is obtained in the pure form by van Arkel method. Zirconium is also obtained by this method. Aluminium is purified by either Hall's process or
Baeyer's process or Serperck's process. Mond's process is used for
refining nickel. Silicon is refined by zone refining.
