Solution
The correct option is A 2
Significant figures are meaningful digits which are known with certainty plus one which is estimated or uncertain. The uncertainty is indicated by writing the certain digits and the last uncertain digit.
The zeros written to the left of the first non-zero digit in a number are non-significant. They simply indicate the position of the decimal point.
Hence, there are 2 significant figures in 0.0025
