Expert Answer:

Structure (I) is more basic than structure (II) as the lone pair of electrons on nitrogen in structure (II) are involved in the aromaticity of the ring or say they are swimming in the ring and not readily availabale for donation while the lone pair of elecrtons on nitrogen in structure (I) are readily available for donation.
More the electron donating property of the molecule, more is the basicity.
