The elements that both have chemical symbols that are two letters and start with the letter "S" are:

Tin (Sn) and Antimony (Sb)

However, the correct response based on the requirement of starting with "S" should mention Silicon (Si) and Sulfur (S) as options. Since these specific elements are not provided in your list, let's analyze your options:

  1. Silver (Ag) and Lead (Pb) - Chemical symbols do not start with S.
  2. Potassium (K) and Tungsten (W) - Chemical symbols do not start with S.
  3. Tin (Sn) and Antimony (Sb) - Only Tin starts with S, Antimony does not.
  4. Mercury (Hg) and Iron (Fe) - Chemical symbols do not start with S.

Given the choices provided, none of the responses meet the criteria of having both symbols starting with "S."
