the correct option is c.

isotopes refers to different forms of the same element with the same atomic number but different mass number as a result of difference in their neutron numbers. isotopes have different relative atomic mass but share the same chemical properties.

the electron configuration that you gave me has 16 electrons ergo it has 16 protons ergo it is the element sulfur.
