Salt bonds account for what fraction of the hair's overall strength?

  1. One quarter

  2. One third

  3. One half

  4. Three quarters

The correct answer is: One third

Salt bonds account for one third of the hair's overall strength. This is because salt bonds are weaker than disulfide bonds, which make up the other two thirds of the hair's strength. This means that although salt bonds play a significant role in the hair's strength, they are not the primary contributor. Option A and D, both representing one fourth and three fourths respectively, are incorrect as they do not accurately reflect the role of salt bonds in hair strength. Option C, representing one half, is also incorrect as it does not take into account the contribution of disulfide bonds. Therefore, option B is the most accurate answer.
