Answer:

Three.

Explanation:

When counting the number of significant figures in a decimal number, you start counting from the right of the decimal point.

#cancel0color(red)(.00203)#

Counting from left to right from the decimal point , there are 5 digits.

However, the zeroes before any natural number is not counted as a significant figure.

#cancel(0.00)color(red)(203)#

Thus, there are #color(red)3# significant figures ie. 203.

Note: any other numbers added to the right of #0.00203# is also counted as a significant number.

eg. #0.002031# has 4 significant figures.
eg. #0.002030# has 4 significant figures.
