How do we compute the voltage gain of a simplified CB amplifier model using hybrid parameters?

(a) hfe × RL / hie

(b) -hfe × RL / hie

(c) hfe × RL / hoe

(d) -hfe × RL / hoe

I had been asked this question in examination.

My question is taken from Simplified Calculations for the CB Configuration topic in portion Low Frequency Transistor Amplifier Circuit of Electronic Devices & Circuits

The correct option is (a) hfe × RL / hie

Easiest explanation: The voltage gain of a simplified common base (CB) amplifier can be expressed in terms of approximate hybrid parameters. The voltage gain is equal to hfe × RL / hie where, RL is load resistance, hie is input resistance of CE amplifier and -hfe is the current gain of CE amplifier.
