Which line of dialogue use’s correct punctuation? A. “Don’t be silly, said Jill.” B. No one takes those seriously, said Jill. C. “But there’s a no trespassing sign “, Maria argued. D. “I’m not sure it’s a good idea to be here ,” said Maria.

Hmm, let me clown around with the options and see which one makes us laugh the most while being grammatically correct.

A. "Don't be silly," said Jill.
B. "No one takes those seriously," said Jill.
C. "But there's a 'no trespassing' sign," Maria argued.
D. "I'm not sure it's a good idea to be here," said Maria.

Well, while option C tries to sneak in some extra quotation marks, the use of single quotation marks is not clown-approved. So, the correct answer is option B: "No one takes those seriously," said Jill. It's got the right punctuation and gets the point across without causing any clown confusions!

The line of dialogue that uses correct punctuation is D. "I'm not sure it's a good idea to be here," said Maria.

The line of dialogue that uses correct punctuation is A. "Don't be silly," said Jill.

To determine which line of dialogue uses correct punctuation, let's analyze each option:

A. "Don't be silly," said Jill.
In this option, there is a comma inside the quotation marks following the dialogue "Don't be silly," and the final period is placed before the closing quotation marks. This is the correct placement of punctuation for dialogue.

B. No one takes those seriously, said Jill.
In this option, there is no punctuation within the quotation marks to separate the dialogue from the speaker attribution. It should have a comma, so it is not correctly punctuated.

C. "But there's a no trespassing sign ", Maria argued.
In this option, there is a space before the closing quotation mark, which is incorrect. The period should be placed inside the quotation marks. Additionally, there should be a comma following the speaker attribution. Therefore, it is not correctly punctuated.

D. "I’m not sure it’s a good idea to be here ," said Maria.
In this option, there is a space before the closing quotation mark, which is incorrect. The comma should be placed inside the closing quotation mark. Additionally, there should be a comma following the speaker attribution. Therefore, it is not correctly punctuated.

Therefore, the correct answer is option A. "Don't be silly," said Jill.
