One of these is not the use of an electroscope
testing the type of charge on a charge body
measuring ionization current in air
detecting the pressure of charge on a charged body
producing electric charge in a body
Explanation
Measuring ionization current in air:
This is typically not a function of an electroscope. While it can detect charge, it does not measure ionization currents, which require specialized equipment like an ionization chamber.
