Options

A. Marigold
B. Daffodils
C. Lily
D. Beans

Answer

**Step-by-Step Solution:**

1. **Understanding Golden Rice**: Golden rice is a genetically modified (transgenic) variety of rice that has been engineered to produce beta-carotene, a precursor of vitamin A. The scientific name of rice is *Oryza sativa*.

2. **Identifying Beta-Carotene**: Beta-carotene is the compound responsible for the yellow color of the rice grains and is known as provitamin A, which means it can be converted into vitamin A in the body.

3. **Source of Beta-Carotene**: The genes responsible for the synthesis of beta-carotene in golden rice were derived from specific plants. In this case, the correct source is the temperate garden of daffodils.

4. **Eliminating Incorrect Options**:
- Marigold is not the source of beta-carotene for golden rice.
- Daffodils are indeed the correct source.
- Lilies and beans are also not sources of beta-carotene for golden rice.

5. **Conclusion**: The correct answer to the question is that alpha-carotene, which was mistakenly mentioned, should actually refer to beta-carotene, and it is isolated from daffodils.

**Final Answer**: The Golden rice was created by transforming rice with beta-carotene, which was isolated from daffodils.
