Answer: blood to fat.

Explanation: The wavelength λ = v/f and the frequency f stays the same across tissue boundaries, so the change in wavelength is proportional to the change in wave speed. Differences:
- muscle–kidney: 1580–1560 = 20 m/s
- liver–muscle: 1580–1550 = 30 m/s
- fat–liver: 1550–1450 = 100 m/s
- blood–fat: 1570–1450 = 120 m/s

Largest change = 120 m/s (blood to fat).
