"Eventually" means in the end, after a period of time or delay. It expresses the idea that something happened after other things or after some effort or time had passed.

A. soon – means in a short time from now, which implies quickly, not after a delay.

B. lately – means recently, not the same as eventually.

C. subsequently – means afterward, used in describing a sequence of events, but not necessarily after a long wait or effort.

D. frequently – means often, which is unrelated in meaning.

E. finally – means at last or after a long wait or delay, which is closest in meaning to "eventually."
