The wavelength ($\lambda$) of ultrasound waves in tissue can be calculated using the formula $\lambda = \frac{v}{f}$, where $v$ is the speed of sound in the tissue (approximately 1540 m/s for soft tissues) and $f$ is the frequency of the ultrasound wave. For a 2.0 MHz ultrasound, $\lambda = \frac{1540}{2.0 \times 10^6} = 7.7 \times 10^{-4}$ m, which is closest to option A, 7.5 × 10^-4 m.
