Answer 1

The correct option is C A- (IV), B- (I), C- (V), D- (II)

The apices of these underground branches store food materials and become tuberous. These are called stem tubers. In Stachys tubifera, the reserve food is stachyose.
the underground branches grow obliquely upward from the axillary buds of nodes present below the soil. These underground branches are called suckers. For example, Chrysanthemum and Mentha.
In some plants, the long slender branches which arise from the base of the stem grow obliquely downwards. When these branches touch the soil, they produce adventitious roots. These branches are called stolons. For example, jasminium and Rosa.
In some weak stemmed plants, the stem creep on the soil and are rooted at every node. When the internode break off, the nodes lead an independent life. These weak stemmed plants are called runners. For example, Hydrocotyl vulgaris.
Thus, the correct answer is option (C).
