there is an option duration after all! and it is
duration of option = (options delta x duration of underlying x price of underlying)/price of option
and btw another sneaky formula from bonds is when we want to replace an old bond with a new one..
value of new bond = (Dollar Duration of old bond/Duration of new bond) x 100
imagine we see these on exam day!
 
its easier if you look at it as
delta of option = (duration of opt * price of option)/(duration of underlying * price of
underlying_
 
It it that this is applicable to I/R option only ?

OK. OK. I always take Duration as Delta change. For FX derivatives, FX Delta.
 
What page did you find this on of CFA text? … and is there any mention of option beta?
 
Option duration is mentioned in 30f - fixed income portfolio management II.
