Answer :
We start with the division:
[tex]$$ \frac{12.0}{7.11} \approx 1.688. $$[/tex]
Since both the numerator (12.0) and the denominator (7.11) have 3 significant figures, the result should be expressed with 3 significant figures as well. To round 1.688 to 3 significant figures, we look at the fourth digit (which is 8) to decide how to round the third digit. Rounding 1.688 to 3 significant figures gives:
[tex]$$ 1.69. $$[/tex]
Thus, the correct answer is:
[tex]$$ \boxed{1.69}. $$[/tex]
