A complex sentence has one dependent clause and one independent clause.
Here's some examples;
1. After twenty years, he still had feelings for her.
2. Because my coffee was too cold, I heated it in the microwave.
C- The additional meaning that comes from the feelings one gets from a word is the correct answer.
The first one and the last 2 any of those would be right because you can take sides and be for or against it and argue why...
I hope this helps! /!
The answer is d does not follow scheme because lines 1 and 3
