Answer: (A)

Verified step by step guidance

1. Recall that the number of protons in an atom is given by its atomic number (Z), which is unique for each element.
2. Identify the element sulfur on the periodic table to find its atomic number.
3. Note that sulfur has the atomic number 16, meaning it has 16 protons in its nucleus.
4. Understand that the atomic number (number of protons) defines the element and does not change for atoms of that element.
5. Therefore, the number of protons in a sulfur atom is equal to its atomic number, which is 16.
