What does accent on second syllable in a word mean?

1 : an effort in speech to stress one syllable over adjacent syllables also : the stress thus given a syllable a word with the accent on the second syllable.

Choice A and C is out instantly- the topic is already clear (having growth epxeriences) and the sentence 3 is boring doesn't make much an improvement (in my opinion).
