The central idea of this passage would be C. This is because thee passage states, "So, living in a landlocked city doesn't have to keep people from enjoying the water." Hope this helped! BTW it would help be a lot it if you gave the the most "brainliest" answer award.
"Sea-scented beach" is an example of both alliteration and assonance due to the fact that, (alliteration) you have two repeating consonants "<em>s</em><em />ea-<em>s</em><em />cented..." and assonance because of the "ea" in sea, and the "ea" in beach make the same sound.
