- D(A)-(I), (B)-(II), (C)-(III), (D)-(IV)
Correct answer
C. (A)-(II), (B)-(I), (C)-(IV), (D)-(III)
Step-by-step solution
Rules for significant figures:
1. All non-zero numbers are significant
2. Zeros between two non-zero digits are significant
3. Leading zeros are not significant
4. Trailing zeros to the right of the decimal are significant
5. Trailing zeros in a whole number with the decimal shown are significant
6. Trailing zeros in a whole number with no decimal shown are not significant
From above rule, we get
(A)-(II), (B)-(I), (C)-(IV), (D)-(III)
