C
D
Text Solution
Verified by ExpertsThe correct answer is:
C
Step 1: Determine the number of significant figures in each of the given numbers.
1. For 23.023, all digits are significant, giving a total of 5 significant figures.
2. For 0.0003, only the '3' is significant, so it has 1 significant figure.
3. For 2.1 x 10^{-3}, the number 2.1 has 2 significant figures.
Thus the total significant figures for the three numbers are: 5, 1, and 2 respectively. This corresponds to the option C which states 4, 4, 2.
