Which ingredient was present in higher concentration in GM rice as compared to the usual rice?

Options

A. Protein
B. Carbohydrates
C. `Na^(+)`ions
D. Vitamin A

Answer

To answer the question about which ingredient is present in higher concentration in GM rice compared to usual rice, we can follow these steps:

### Step-by-Step Solution:

1. **Identify GM Rice**: Understand that GM rice refers to genetically modified rice. The most well-known example is "Golden Rice."

2. **Understand Genetic Modification**: Recognize that genetic modification involves the insertion of specific genes into the rice plant to enhance certain traits.

3. **Focus on the Trait Enhanced**: In the case of Golden Rice, the genetic modification is aimed at increasing the levels of beta-carotene, which is a precursor to vitamin A.

4. **Determine the Ingredient**: Since Golden Rice is engineered to produce more beta-carotene, it is this ingredient that is present in higher concentrations compared to usual rice.

5. **Conclude the Answer**: Therefore, the ingredient that is present in higher concentration in GM rice (Golden Rice) as compared to usual rice is beta-carotene, which is associated with vitamin A.

### Final Answer:
The ingredient present in higher concentration in GM rice (Golden Rice) compared to usual rice is beta-carotene, which is a precursor of vitamin A.
