b. Always ask yourself this question: “ Am I pleased with the results?”
A colon should be used when there is a complete sentence before it. In option B, "Always ask yourself this question" is a complete sentence.
Option A is incorrect because after "yourself" your brain automatically wants to say "is ...". Option B is incorrect because the quotation is embedded within the sentence so there should not be any punctuation after "is". Option D is also incorrect. There should not be any punctuation after the word "like" either.
No, you dont "need this quick". you need to do your own homework. it's number one, take the two seconds it takes to do your own homework instead of botherig us. please.
