The correct option is A

Roots

Seeds are soaked overnight and drained. When the seed is full enough, it pops open. The primary root or radicle is the first part of the embryo to emerge. It grows down into the soil to anchor the plant and deliver nutrients and water. Next, the stem or the plumule emerges, with the cotyledon on top. It can look like a tiny leaf or a fleshy bean. The cotyledon provides food to the growing plant until it can make its own food through photosynthesis.
