To determine the concentration percentage of a solution, you can use the formula:

\[

\text{Concentration (\%)} = \left( \frac{\text{mass of solute (g)}}{\text{volume of solution (mL)}} \right) \times 100

\]

In this case, the mass of the sugar (solute) is 134 g, and the volume of the solution is 200 mL. Plugging these values into the formula gives:

\[

\text{Concentration (\%)} = \left( \frac{134 \, \text{g}}{200 \, \text{mL}} \right) \times 100 = 67\%

\]

This means that the solution is composed of 67 grams of sugar per 100 mL of solution, leading to a concentration of 67%. This calculation confirms that option 67% is indeed the correct answer.

Other percentage options do not accurately reflect the relationship between the mass of the sugar and the volume of the solution as calculated.
