Which of the following is a good source of carbohydrates?

Pasta and bread are excellent sources of carbohydrates because they are primarily made from grains that contain starch, which is a complex carbohydrate. Carbohydrates are one of the body's main energy sources, providing fuel for daily activities and essential bodily functions. Grains, such as those found in pasta and bread, are rich in starch, which gets broken down into glucose during digestion and is utilized by the body for energy.

While other options like fruits and vegetables do contain carbohydrates, they often provide a mix of sugars and fiber rather than being as concentrated solely in starch as pasta and bread. Wholemeal bread is also a great carbohydrate source but is a more specific example within the broader category of "pasta and bread." Meat, on the other hand, is primarily a source of protein and does not contain significant carbohydrates. This illustrates why pasta and bread are highlighted as particularly strong carbohydrate sources.
