Hey there!
Here is your answer:
The proper answer to this question is option C "0.00349".
Reason:
1 L = 100 cL. Or 1 cL = 0.01 L
34.9 cL = 34.9 / 100 L = 0.349 L
1 hL = 100 L. 0.349 L = 0.349 / 100 hL = 0.00349 hL
Therefore the answer is option C!
If you need anymore help feel free to ask me!
Hope this helps!
