Answer: Option A
The phrase "blamed for" is a common expression in English, which means to hold someone responsible for something negative or unpleasant that has happened. In the given sentence, John is the subject who is being blamed, and "the accident" is the object for which he is being blamed. Therefore, the correct preposition to use with "blamed" in this sentence is "for."
To understand this concept more clearly, let's first define some relevant terms:

• Preposition: A preposition is a word that shows the relationship between a noun or pronoun and other words in a sentence. Common prepositions in English include "in," "on," "at," "to," "with," "from," and "for," among others.
• Object: In grammar, the object is a noun or pronoun that receives the action of the verb in a sentence. In the given sentence, "the accident" is the object of the verb "blamed."

The correct preposition to use with "blamed" depends on the context of the sentence. Some common prepositions that can be used with "blamed" include "for," "on," "with," and "about." Here's a brief explanation of each:

• Blamed for: This means that someone is held responsible for a negative event or outcome.
• Blamed on: This means that someone is accused of causing a problem or difficulty.
• Blamed with: This means that someone is accused of using a particular object or tool to cause harm or damage.
• Blamed about: This means that someone is criticized for their actions or behavior.

In the given sentence, John is being held responsible for the accident, which makes "for" the appropriate preposition to use with "blamed." The sentence can be rewritten as "John was later blamed for the accident."
Formula:Blamed + preposition + object
In conclusion, the correct answer to the given question is Option A: for, which is the most appropriate preposition to use with "blamed" in the given sentence.
