Ok so I am positive the answer is the lesson/moral of the story this is because when searching upon what the theme is; the theme is the message or meaning the work (or story) is trying to communicate (or tell) you. Hope this helps oiiiiiiii!!!!!!!!!
First, you have to talk to your crush a lot (through any social media apps and in real life) and get to know her really well. Then, you gotta take her on a date (maybe saying like, "What are you doing this weekend?") If your crush isn't going anywhere, you can ask him/her to go to an interesting place that would entertain him/her. If everything went well, you gotta build a relationship with him/her until you finally asks him/her to be your boyfriend/girlfriend. Then, he/she might be your fiance one day and have a family.
The End.
The answer is C , because the other sentences end in 3rd person. C starts and ends in first person, therefore C is the correct answer.
The correct answer is B, as the other choices have words in incorrect tenses.
