Power transistors have higher operating frequency view lower switching losses. Also the reverse recovery time is smaller amounting to lower switching time. I think option C is correct for this question.

What is the use high dv/dt rating?

Power transitor are faster than SCR.

I think the Transistor has an advantage in SCR in terms of time so it should be c because the lower the value the fastest switching time.
