Options

  1. A(A)-(III), (B)-(IV), (C)-(II), (D)-(I)
  2. B(A)-(IV), (B)-(III), (C)-(I), (D)-(II)
  3. C(A)-(II), (B)-(I), (C)-(IV), (D)-(III)
  4. 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)
