Which of the following is a correct representation of significant figures?

Which of the following is a correct representation of significant figures?

Step 1: Identify the number given, which is 0.00450.
Step 2: Understand that leading zeros (the zeros before the first non-zero digit) do not count as significant figures. In this case, the leading zeros are 0.00.
Step 3: Look at the non-zero digits in the number. The first non-zero digit is 4, followed by 5.
Step 4: Check for any trailing zeros (zeros after a non-zero digit) that are to the right of the decimal point. Here, there is a trailing zero after the 5.
Step 5: Count the significant figures. The digits 4, 5, and the trailing zero are all significant, making a total of 3 significant figures.
