let
x---------> Aviva’s age
y--------->Kanti’s age
z--------> Lakshmi’s age
we know that
y=x-3-----> equation 1
z=2*y-----> equation 2
substitute equation 1 in equation 2
z=2*(x-3)
so
Aviva’s age------> x
Kanti’s age-------> x-3
Lakshmi’s age----> 2*(x-3)
therefore
the answer is the option
b) 2(x-3)
