Phreatophytes are the plants adapted to grow in

The correct answer is (a). Phreatophytes are plants that have adapted to grow in moist, shaded places. They have long roots that reach down to the water table, which is the level below the ground where the water is always present. This allows them to get the water they need even when the surface soil is dry.

(b) Rocky environments are not ideal for phreatophytes because the rocks can block their roots from reaching the water table.

(c) Arid environments are also not ideal for phreatophytes because there is not enough water available for them to grow.

(d) Active volcanic lava is too hot and unstable for phreatophytes to grow.
