A Correct answer
Explanation

Statement (a) is true. Junction field effect transistors like BJTs are three lead semiconductor devices. Statement (b) is false. JFETs are normally ON when VG - VS = 0. Statement (c) is true. Unlike BJTs, JFETs do not require a bias current and are controlled by using only a voltage.
