A misplaced modifier refers to a word, phrase, or clause that is positioned in an incorrect place in a sentence, which leads to confusion or ambiguity. To determine which sentence has a misplaced modifier, we need to examine each sentence and identify any modifiers that may be misplaced.

1. "When looking out the window, they say the first leave fall."
This sentence does not have a misplaced modifier because the modifier "When looking out the window" is correctly modifying the verb "say."

2. "They gave sandwiches to the children on paper plates."
This sentence does not have a misplaced modifier. The phrase "to the children" appropriately modifies the verb "gave."

3. "On the way to the store, she saw a lost cat."
This sentence does not contain a misplaced modifier as the introductory phrase "On the way to the store" properly modifies the verb "saw."

4. "The boy received a dog named Rover for his birthday."
This sentence contains a misplaced modifier. The phrase "named Rover" should ideally be placed closer to the noun it modifies, "dog," resulting in "The boy received a dog named Rover for his birthday."

Therefore, the sentence with the misplaced modifier is: "The boy received a dog named Rover for his birthday."
