• A. one
• B. two
• C. three
• D. four
• E. five

Answer 1

The Correct Option is C

Step 1: In the value 0.0500L, the zeros following the decimal point but preceding non-zero digits are not counted as significant. 
Step 2: The two zeros after the non-zero digits '5' are significant because they are trailing zeros in a decimal portion of the number. 
Step 3: Therefore, there are three significant figures (5, 0, 0) in the measurement 0.0500L.
