I would choose answer C.
this is because the format of the essay is been informative, and that sentence was opinion orientated, while all the other options presented statistics.
<span>A conversation between two or more people in a story or play is called 'dialogue.' </span>
The theme is how you tell the structure of a poem
Hope this helps

Although introduction of characters may contribute suspense, depending on the way the character is created, <span> </span>making<span> your readers worry about all the </span>ways<span> your hero's plans is still the best way to build suspense.</span>
