Henry's Law is used in scuba diving to understand the effects of changes in pressure on the solubility of gases in the blood. The following statements are true regarding the application of Henry's Law in scuba diving:

a) Scuba divers must inhale compressed air containing nitrogen and oxygen.

b) The solubility of nitrogen in the blood increases as the pressure increases.

c) Rapid ascent of a scuba diver can cause nitrogen bubbles to form in the blood, leading to decompression sickness.

However, option d) is not true as nitrogen is more soluble in blood than oxygen. This is why nitrogen bubbles can form in the blood during a rapid ascent, but not oxygen bubbles.

Therefore, the correct answer is d) Oxygen is more soluble in blood than nitrogen.
