What on-the-go option does IHOP offer?

The option highlighting pancake house meals in portable packaging is the correct choice as it reflects IHOP's approach to providing convenient dining solutions for customers who are looking for meals that they can enjoy on-the-go. This option demonstrates IHOP's adaptation to modern eating habits, where many people prefer or require meals that are easy to transport. The portable packaging enables customers to enjoy their favorite IHOP offerings, such as pancakes or other breakfast items, even when they are busy or traveling.

In contrast, the other options, while they may represent popular food items, do not specifically encapsulate the core offering of IHOP’s on-the-go initiative in the same way. Breakfast burritos and breakfast sandwiches are traditional fast food items but do not fully highlight IHOP's unique identity centered around pancakes and breakfast meals. Likewise, fruit smoothies, while healthy and convenient, do not represent the signature meal offerings that IHOP is known for, which are being innovatively provided in portable formats.
