    The answer to your question is the letter C.

    Explanation:

    Data

    2NaCl

    When we write molecules we use numbers in two main different ways.

    If the coefficients are at the beginning of the molecule, this number indicates the number of molecules presented.

    If there are subscripts, this number indicates the quantity of that specific element.

    So the correct answer is letter C because it describe the correct function of this coefficient.
