Sorry for my late reply. Thanks for your comments, I was successful in the calculation of the polarizability of C6H6.

DFT Linear Response polarizability / au
Frequency  =       0.0773150 / au
Wavelength = 589.3209985 / nm
X Y Z
-----------------------------------------------
X 64.1637914 -0.0002708 -0.0000000
Y -0.0002713 64.1628593 0.0000000
Z -0.0000001 0.0000001 22.9828814
-----------------------------------------------
Eigenvalues = 64.1638644 64.1627863 22.9828814
Isotropic = 50.4365107
Anisotropic = 41.1804440
-----------------------------------------------

The input file is as follow.
