(c)

Stolons are special kind of runners, which initially grow upwards like ordinary branches and then arch down to develop new daughter plants on coming in contact with the soil.

Sucker is a sub-aerial branch, that arise from the main stem. Initially, it grows horizontally below soil surface and later grows obliquely upward.
