Answer:
B.
Step-by-step explanation:
as for my answer please correct if im wrong
The answer is three significant figures. The 1 and the 7 are both significant, because they are non-zero quantities.
This is where significant figures gets a little more complicated, because if a zero is used as a placeholder (i.e. 0.00027 cm) then it is insignificant.
But in the case above, the zero isn't being used as a placeholder, and thus, is significant.
It is either 2/10 or .20 or 20%. idk know what your answers to choose from are
