Answer :
The correct phrase to follow the statement "¿Qué nos recomienda para cenar" is: b. la sopa de tomate.
The phrase "¿Qué nos recomienda para cenar?" asks for a dinner recommendation. The most suitable response is "b. la sopa de tomate." This option provides a specific suggestion ("tomato soup") that directly addresses the question.
The other options lack grammatical correctness or coherence. For instance, "a. Les recomiendo que coman" is incomplete and lacks specificity, while "c. la sopa de tomate" lacks the necessary verb and connection to the question. "d. la sopa de tomate" is grammatically correct but lacks the context provided by the question, making it less appropriate as a response. Therefore, option b is the most fitting response to the query.
