Hello there!

Your correct answer would be the (last option, option d). The reason to why Luka’s measurements are more accurate, but Anja’s measurements are more precise would be because if you have noticed, Luka's is rounded to the answer, which would make this accurate, because it's rounded. But when it is very precise, that would be different, because this would not be accurate, because it would contain a direct number in this situation.

I hope this helps you!
