Which pasta is gluten-free?

The correct choice of gluten-free pasta is gluten-free rotini. This option is specifically designed to meet the dietary needs of individuals who are sensitive to gluten or have celiac disease. Gluten-free pasta is typically made from alternative flours such as brown rice, quinoa, or lentils, which do not contain gluten, allowing those with dietary restrictions to enjoy a pasta dish without adverse effects.

In contrast, whole wheat linguine contains gluten since it is made from wheat flour. Pappardelle and paccheri are also traditional pasta types made from semolina flour, which contains gluten. Thus, the gluten-free rotini is the only option that caters to those avoiding gluten, making it the correct answer.
