![A grayscale diagram showing a legend at the top and two side-by-side rectangular beakers below. The legend defines: a small open white circle represents \(\text{H}^+\); a large solid black circle represents \(\text{X}^-\); a large gray circle represents \(\text{Y}^-\); and a diatomic pair consisting of a small open white circle touching a large gray circle represents an intact \(\text{HY}\) molecule. The left beaker, labeled 'Beaker 1: \(\text{HX}\)', contains exactly 6 separate small open white circles and exactly 6 separate large solid black circles evenly dispersed throughout the liquid volume. The right beaker, labeled 'Beaker 2: \(\text{HY}\)', contains exactly 5 intact diatomic pairs, exactly 1 separate small open white circle, and exactly 1 separate large gray circle evenly dispersed throughout the liquid volume. No other particles, labels, text, or annotations appear.](https://nerd-notes.com/wp-content/uploads/ubq-frq-generated/stem-fig-1-1790598634-KZdKoU.jpg)

- **A.** Solution \(\text{HX}\) has a higher electrical conductivity than solution \(\text{HY}\), and equal volumes of \(\text{NaOH(aq)}\) are required to reach the equivalence point for both solutions.
- **B.** Solution \(\text{HX}\) has a higher electrical conductivity than solution \(\text{HY}\), but a greater volume of \(\text{NaOH(aq)}\) is required to reach the equivalence point for solution \(\text{HX}\) than for solution \(\text{HY}\).
- **C.** Solutions \(\text{HX}\) and \(\text{HY}\) have equal electrical conductivity, and equal volumes of \(\text{NaOH(aq)}\) are required to reach the equivalence point for both solutions.
- **D.** Solutions \(\text{HX}\) and \(\text{HY}\) have equal electrical conductivity, but a greater volume of \(\text{NaOH(aq)}\) is required to reach the equivalence point for solution \(\text{HX}\) than for solution \(\text{HY}\).
