Answer:
C
Step-by-step explanation:
1)Non- zeros (1,2,3,....) are always significant.
2)Captive zeros are significant too( zeros between non- zeros ).
3)Trailing zeros (zeros at the end) aren't significant always unless if there is a decimal point.
Such this question we have decimal point so we count them
