Hellenism can best be described as the a. spread of persian culture in the world. b. influence and spread of greek culture in the world. c. resistance to greek culture in the world. d. cause of the war between troy and sparta.

B. The exact definition being "the study or imitation of ancient Greek culture."

The correct answer is B. influence and spread of Greek culture in the world. 

Option A is actually quite the opposite since Persians fought against the Hellenistic culture. Resistance to Greek culture is also the opposite since it would be resisting Hellenistic tendencies. The cause of the war between Troy and Sparta was actually seen in myths where Paris gave the Apple of discord to the goddess that promised him Helen.
