Verified step by step guidance

1. Step 1: Understand the concept of carbohydrates. Carbohydrates are classified into two main types: simple carbohydrates and complex carbohydrates. Simple carbohydrates include sugars like glucose, fructose, and sucrose, while complex carbohydrates are made up of long chains of sugar molecules, such as starches and fibers.
2. Step 2: Identify the characteristics of complex carbohydrates. Complex carbohydrates are typically found in whole grains, vegetables, and legumes. They provide sustained energy because they take longer to break down in the digestive system compared to simple carbohydrates.
3. Step 3: Analyze the options provided in the question. Glucose tablets, table sugar, and honey are examples of simple carbohydrates because they consist of short sugar chains or single sugar molecules. Brown rice, on the other hand, is a whole grain and contains starch, which is a complex carbohydrate.
4. Step 4: Recall that complex carbohydrates are nutritionally beneficial as they often contain fiber and other nutrients. Brown rice, being a whole grain, fits this description and is a source of complex carbohydrates.
5. Step 5: Conclude that brown rice is the correct answer because it is a complex carbohydrate, while the other options are simple carbohydrates.
