When i wake up in the morning i will flip and flop before i get out of bed. Then my mom will blow me a kiss before I get on the bus for school. before class starts I get to play on the playground. after school is done I rush to my house and wait for my dad to come home. my family will eat a good dinner then go to bed.
To my mind, the answer ( B ) is the inappropriate sentence. In a formal writing informal tone must be avoided as well as colloquial expressions.
