Answer

To answer the question "Leaf in the axil of which flower arises?", we need to analyze the options provided:

1. **Sporophyll**: These are leaves that bear sporangia, which are structures that produce spores. They are not specifically related to the axil of a flower.

2. **Bract**: A bract is a modified leaf that is often associated with a flower or flower cluster. It is located in the axil of the flower and can sometimes be mistaken for a petal. This option is relevant to the question.

3. **Hypsophyll**: This term refers to leaves that are found beneath the sporophylls. It does not relate directly to the axil of a flower.
