      The most abundant element in earth’s crust is Oxygen. But, it is not given in the choice.
      The second most abundant element in earth’s crust is Silicon, Si.
      Hence, the correct choice among the given is same. You must be careful while choosing the correct option. So think twice. Best wishes for your Success in the Exam.
