The SI units are rational, coherent, universal and more simple than the older systems.
The correct answer doesn't appear in the list of choices.Each of those three quantities CAN be describes in SI units.
There are 7 base SI units and all other are defined using these 7 base units. See the related question below:[http://wiki.answers.com/Q/What_are_all_the_SI_unitsWhat are all SI units?]
It's much easier to convert units in the SI system.Don't look now, but the SI system is the "everyday" systemin virtually the whole world outside the USA.

In the International System of Units (SI Units), time is measured in seconds.

Any advantage, only confusions and errors.The SI is strongly recommended.

If you have different units, converting to any common unit will help. Of course, using standard units, i.e. SI units, is better than any other arbitrary unit. Also, SI units for a consistent set of units; as a result, you can often omit proportionality factors from formulae.

Different SI unit help us to identify the thing of which the SI unit is. It also help others countrymen to know and so that they can cooperate with other countrymen
The main advantage is that if you stick to SI units, the formulas are simpler, without having to multiply/divide with strange constants. Joule = Newton x meter Watt = joule / second This is simpler than using calories for energy, since a calorie is 4.184 joules
