Rhizome - Dryopteris, Nelumbo nucifera
Corm -Crocus sativus, Amorphophallus
Sucker - Curcuma domestica, Zingiber officinale
Tuber - Helianthus tuberosus, Solanum tuberosum
Sucker is an adaptation in which the stems arise from the underground, grow horizontally and promote asexual reproduction at a neighbouring site. At the new site, it will give rise to a new aerial shoot or crown. The process is repeated. Each sucker has one or more nodes with scale leaves and axillary buds, e.g., Chrysanthemum. Curcuma domestica and Zingiber officinale are the examples of rhizomes and hence the correct answer is option C.
