I'd say b, precise, here.
If there's an error somewhere in the experiment or project, then it is consistently .... wrong. So, just 'cos you measure something precisely, it doesn't mean that you've measured it accurately. Maybe an example would be a measurement of length. If you used a metal ruler at zero degrees C, you can measure to say half a millimetre. A series of measurements of the same object would give very similar readings. But, if you used same metal ruler at, say 100 celsius (implausible) then you'd probably get a different set of readings. 'cos of the expansion of the metal ruler.
Answer:
Due to the chemical versatility of carbon atoms
Explanation:
Carbon is a very important element and it is commonly found in many varieties of chemical compounds. They are also found to be present in space in various amount. It is often considered to be versatile because they are capable of forming single, double, as well as triple bonds. This enables them to make single and branched chains. They also form ring chains when combined with other atoms of carbon.
It is because of this versatility of carbon atoms, there forms complex variety of organic molecules.

Answer:
0.6 m/s
Explanation:
1.8 km = 1800 m
5 minutes= 300 s
Now,
Velocity = Displacement / time
= 1800/300
= 0.6 m /s
