Which sentence shows the correct placement of punctuation?
a “my mood is always better”, bette said, “after my morning run.”
b “my mood is always better bette said, after my morning run”.
c“my mood is always better,” bette said, “after my morning run.”
d “my mood is always better bette said, after my morning run.”

The answer would be C. In a sentence like this, you always have to remember to put punctuation inside the quotation marks.  And "My mood is always better, after my morning run." is what Bette is saying, so those would stay in quotes, while Bette said, would be outside of the quotation marks. This is why C would be the answer, if you need more information on this question, I'm more than happy to help you.

B." to guard against " is correct answer
