The correct answer is B. Bob and Joe got into Joe's car.
Step-by-step explanation:
For a sentence to be considered as correct it needs to contain a subject and a verb, express a complete ide and follow language and writing standards. According to this only the sentence "Bob and Joe got into Joe's car" is correct because this expresses a complete idea and contains a subject (Bob and Joe) and a verb (got). Additionally, this sentence is grammatically correct especially in the use of the apostrophe (') to express belonging as this clarifies the car belongs to Joe and both Bod and Joe got in the car. On the other hand, in other options, there is no complete idea or there are grammatical mistakes.
