From the description given below, identify the type of stem modification.
A lateral branch arises from the basal, underground part of the main stem. It grows horizontally for a distance under the soil and then emerges obliquely upwards.

The correct option is A Sucker
In subaerial modifications, the stem is partly aerial and partly underground. Short aerial branches and adventitious roots develop at the nodes. Detachment of entire branch or a node can develop into a new plant. Sucker is a type of sub-aerial stem modification. It arises from the basal, underground part of the main stem. It grows horizontally for a distance under the soil and then emerges obliquely upwards. It develops a leafy shoot and adventitious roots before separating from the mother plant. Runner, another sub-aerail stem modification, is a creeping stem with long internodes, running horizontally on the soil surface. The nodes bear axillary buds, scale leaves and adventitious roots. Runner arises from an axillary bud. It is a weak lateral branch that arises from the base of main stem. After growing aerially for some time it bends downwards to touch the ground, where its terminal bud gives rise to a new shoot and adventitious roots. Stem tuber is an underground stem modification for food storage.
