What is one essential ingredient in pasta primavera?

The selection of the first option as the correct answer is suitable because it highlights the traditional components of pasta primavera, which is a dish known for its variety of fresh, seasonal vegetables. Pasta primavera typically includes pasta paired with a mix of vegetables like spinach, onions, mushrooms, and diced tomatoes, creating a light and colorful meal. The inclusion of a sauce, such as Alfredo, enhances the dish while allowing the vegetables to remain the focal point.

In contrast, the other options do not convey the essence of pasta primavera. They either focus on heavier, meat-based sauces and ingredients, like marinara with sausage, or creamy sauces with bacon that deviate from the vegetable-forward concept of primavera. Thus, the first option accurately encapsulates what makes pasta primavera distinctive and authentic.
