A.
If you go faster in a car, you will tend to consume more fuel, but the converse is not necessarily true. In the same way, increased entropy does not necessarily mean greater accuracy of a clock.
B.
The further you go in a car, the more fuel you use. In the same way, the faster you go in a car, the less time you use.
C.
If you measure the speed of a car with a grandfather clock, the result will be different than if you measured it with an atomic clock.
D.
The further and faster you go in a car, the greater the amount of fuel you will use, the greater the amount of heat produced and, hence, the greater the entropy.

Option A is the correct answer.

Explanatory Answer

Note what the passage says before citing the example of fuel usage in a car: 'The relationship that the researchers found is a limit on the accuracy of a clock, so it doesn't mean that a clock that creates the most possible entropy would be maximally accurate'. Just as increased fuel usage in a car does not imply that it is going faster or farther, increased entropy does not mean increased accuracy.
