The correct options are
A Rhizome, underground stem modification
B Ginger, Turmeric
A rhizome is a thick horizontally growing stem which usually stores food material. It has nodes and internodes, scale leaves, axillary buds, adventitious roots and a terminal bud. Scale leaves enclosing the axillary buds are seen arising from the nodal points of the stem. Some of the axillary buds develop into branches which grow upwards into the air and then produce normal green foliage leaves. Usually, the growing points of the rhizome continue to remain underground causing an elongation of the rhizome. Roots develop from the lower surface of the rhizome. Eg. ginger, turmeric.
