Option 1 (seek) -> Plural verb form, but the subject "Ravi" is singular.
Option 2 (seeks) -> Singular verb form that agrees with the subject "Ravi"; correct collocation with "permission."
Option 3 (attempt) -> Doesn't form a proper collocation with "permission."
Option 4 (ask) -> Incomplete collocation; we "ask for permission," not "ask permission."
Hence, Option 2 (seeks) -> In constructions with "as well as," the verb agrees with the first subject (Ravi - singular), not the phrase that follows. "Seeks permission" is also the correct idiomatic expression. -> correct
