In this task, you're given a question, a context passage, and four options which are terms from the passage. After reading a passage, you will get a brief understanding of the terms. Your job is to determine by searching and reading further information of which term you can answer the question. Indicate your choice as 'a', 'b', 'c', or 'd'. If you think more than one option is plausible, choose the more probable option to help you answer the question.
Q: Question: How many drivers were injured during the crash that resulted in DiBenedetto finishing in 28th? Passage:On October 10, 2018, Matt DiBenedetto signed a two-year contract with Leavine Family Racing to drive the No. 95 starting in 2019. In addition, Leavine Family Racing will switch from Chevrolet to Toyota while entering a technical alliance with Joe Gibbs Racing. At the 2019 Daytona 500, DiBenedetto led an impressive 49 laps before Paul Menard spun him from behind, triggering "The Big One" that claimed 21 cars and resulting in DiBenedetto finishing 28th. DiBenedetto scored a career-high fourth place finish at Sonoma. DiBenedetto then scored four more top 10s in the summer months including an eighth at Daytona, a fifth at Loudon, a sixth at Watkins Glen, and a career-high second for both DiBenedetto and Leavine Family Racing at the Bristol Night Race.
