Show answer and explanation

Correct answer: (C) Current-controlled current source

Explanation

The output dependent source supplies current proportional to input current Ii, while the input is an ideal short. Thus the controlling variable and controlled variable are both currents: **current-controlled current source,C**. R models finite output resistance and does not change the source category.
