    in 8085 microprocessor the conditional call instruction take 9 T states where unconditional call takes 18 T states.
    why?

    You have misread the datasheet. The conditional call takes 9 T-states if the condition is FALSE. It takes 18 T-states if the condition is TRUE and the call must be made.
