Final answer:
The Oakland Raiders shared a field with the MLB's Oakland Athletics after 2010, but this ceased after they moved to Las Vegas in 2020. None of the options given in the question are correct.
Step-by-step explanation:
After 2010, the only NFL team that continued to share a field with a MLB team was the Oakland Raiders. They shared the Oakland Coliseum with the MLB's Oakland Athletics. However, this arrangement ended after the 2019 season when the Raiders moved to Las Vegas and became the Las Vegas Raiders, beginning play at Allegiant Stadium in the 2020 season. Therefore, none of the options provided (New York Giants, San Francisco 49ers, Chicago Bears, Miami Dolphins) are correct as of the 2020 NFL season onwards.
