This is a short answer type question as classified in NCERT Exemplar
Inductive reactance XL= 2 L
And capacitive reactance Xc=
For very high frequencies XL= infinity and Xc=0
When reactance of the circuit is infinite it will be considered as open circuit . when reactance of a circuit is zero it will be considered as short circuited.
So C1, C2 = shorted and L1, L2=opened
So Reff= R1+R2
