Answer:
b. 0.75 mm
Explanation:
The distance between antinodes d is half the wavelength 
. We can obtain the wavelength with the formula 
, where f is the frequency given (
) and v is the speed of sound in body tissues (v=1540m/s), so putting all together we have:
which is very close to the 0.75mm option.
