Solution
The correct option is B Sporophyll
A sporophyll is a leaf that bears sporangia. Both microphylls and megaphylls can be sporophylls. In heterosporous plants, sporophylls (whether they are microphylls and megaphylls) bear either megasporangia and thus are called as megasporophylls, or microsporangia and are called as microsporophylls. The dicotyledons, also known as dicots, were one of the two groups into which all the flowering plants or angiosperms were formerly divided. Chlorophyll is the molecule that absorbs sunlight and uses its energy to synthesise carbohydrates from CO2 and water. Monocotyledons, more properly referred to as monocots, are flowering plants whose seeds typically contain only one embryonic leaf, or cotyledon.
Therefore, the correct answer is option B.
