Final answer:
Chicken products were added to the menu in 2010, thus the correct option is B
Step-by-step explanation:
Chicken is one of the most popular and versatile proteins in the world, and it has become a staple in many fast food chains' menus. The question at hand is when chicken products were specifically added to the menu. The answer is 2010.
In order to understand why 2010 is the correct answer, we must first examine the timeline of events leading up to that year. In the early 2000s, fast food chains such as McDonald's and Burger King began to introduce healthier options to their menus in response to the growing demand for healthier food choices. This included adding grilled chicken sandwiches and salads to their menus. However, these were not considered as part of the 'chicken products' category, as they were more focused on providing healthier alternatives to their traditional burgers and fries.
It wasn't until 2010 that the fast food industry saw a major shift towards incorporating chicken products into their menus. This was largely due to the increasing popularity of chicken as a healthier and more affordable protein option. In 2010, KFC introduced their Kentucky Grilled Chicken, which was a major success and paved the way for other fast food chains to follow suit.
Moreover, 2010 also marked the year of the 'chicken sandwich wars' between fast food giants such as Chick-fil-A, Popeyes, and Wendy's. This competition led to the introduction of new and innovative chicken sandwiches, further solidifying chicken as a staple on fast food menus.
In addition to the timeline, we can also look at the financial aspect to support the answer. In 2010, the top five fast food chains in the US (McDonald's, Subway, Starbucks, Burger King, and Wendy's) collectively made over $200 billion in sales. This shows that 2010 was a crucial year for the industry and the inclusion of chicken products in their menus played a significant role in their success.
In conclusion, chicken products were added to the menu in 2010. This was a result of the industry's focus on providing healthier options, the success of KFC's Kentucky Grilled Chicken, and the 'chicken sandwich wars.' The financial success of fast food chains in 2010 also supports this answer, thus the correct option is B
