In which year was Ovid born?

B is the correct choice because Ovid, the renowned Roman poet known for his works such as "Metamorphoses" and "The Art of Love," was born in 43 BC. His birth year is significant in the context of Roman literature, as his works emerged during a time of great political and cultural transformation in Rome. Understanding the timeline of his life helps to appreciate the historical backdrop of his poetry, including the influence of other literary figures and the sociopolitical conditions of the time.

The other years listed do not accurately correspond to Ovid's birth; 40 BC is too early when considering his prolific writing period, and 50 BC is outside the generally accepted range of his birthdate. Similarly, 35 BC would place him well into his early adult life, rather than at the time of his birth. The specificity of 43 BC is important for scholars studying the development of Roman literature and the influences on Ovid's work.
