Question

which sentence is correct?
\the geese look so funny waddling across the road,\ grace giggled.
\the geese look so funny waddling across the road\, grace giggled.

Explanation:

In direct speech, the comma (or other punctuation ending the quoted sentence) should be inside the closing quotation mark. The first option places the comma inside the quotes, which follows the correct punctuation rule for direct speech. The second option incorrectly places the comma outside the closing quotation mark.

Answer:

"The geese look so funny waddling across the road," Grace giggled.
