<h3>What grade are you??? I will answer it but what grade are you?? </h3>
The answer is the bottom choice, 'witching hour, etc'. This is because these are all negative and creepy words, which help to set a very dark theme
I would go for C.Flash forward.
The theme is basically brains over brawn, because the mouse continues to use his intelligence to escape the big and strong creatures that are after him, despite the mouse himself being small and frail.
