Output voltage (Vc) is equal to Vcc - IcRc.
Based on this, we can say that when Ic INCREASES, the product of Ic and Rc increases which will result to a lower Vc where Vcc is held constant.
Voltage gain which is Vo/Vi thus DECREASES. Therefore, they are inversely proportional.

Can Anyone explain clearly?

Isn't the output voltage supposed to be the product of the Ic and Rc?
How does an increase in collector current thereby produce a reduction in output voltage?

A transistor has no voltage gain, a or b -parameters - the ratio of input/output current.

As IC increase the voltage drop through Rc increases therefore output voltage decreases hence voltage gain which is ratio of output voltage to input voltage decreases.
So it is proved that voltage gain is inversely to current gain.
