It would be C because it's the most realistic sentence. In A and B the cat is washing the car, which isn't possible. But, in C Mr. Ruiz is washing the car, and that's realistic.
"The correct option is C. A cat watched Mr. Ruiz washing his car.
The original sentence, Washing his car, a cat watched Mr. Ruiz, contains a misplaced modifier because the phrase washing his car is placed next to a cat, which incorrectly suggests that the cat is washing the car. To correct this, the modifying phrase should be placed next to the noun it is intended to modify, which in this case is Mr. Ruiz.
Let's analyze each option:
A. A cat, washing his car, watched Mr. Ruiz. This option still suggests that the cat is washing the car, which is not the intended meaning.
B. A cat washing his car watched Mr. Ruiz. Similar to option A, this option also incorrectly implies that the cat is washing the car.
C. A cat watched Mr. Ruiz washing his car. This option correctly places the modifying phrase washing his car next to Mr. Ruiz, indicating that it is Mr. Ruiz who is washing the car while being watched by the cat. This sentence does not contain a misplaced modifier and clearly conveys the intended meaning."
The correct sentence that fixes the misplaced modifier is option C: 'A cat watched Mr. Ruiz washing his car.' This clearly indicates that Mr. Ruiz is the one washing the car, while the cat is watching. Options A and B incorrectly imply that the cat is doing the washing.
