    The correct answer is the option: (c) There are 3600 s in 1 h.

    Explanation:

    Hello!

    Let's solve this!

    We will analyze each of the options:

    (a) The speed of light in a vacuum is a physical constant; to six significant figures, it is 299792 x 108 rnis: not an exact number.

    (b) The density of mercury at 25'C is 13.53 g / rriL: not an exact number.

    (c) There are 3600 s in 1 h: it is an exact number since in one hour there are 60 minutes and in one minute 60 seconds, so 60 * 60 = 3600s is an exact number.

    (d) In 2012, the United Slates had 50 stales: not an exact number.

    We conclude that the correct answer is the option: (c) There are 3600 s in 1 h.
