Answer 1

Answer: (D)

a-iii, b-iv, c-v, d-ii

There are various parts of leaf that modifies into tendrils in plants. In plants, either entire leaf, upper leaflets, terminal leaflet, petiole or stipule gets modified into tendril. In Smilax, the stipule is modified into tendril. In Clematis, the petiole is modified into tendril. Tendril performs the function of support and attachment. In Citrus, the first leaf of axillary bud is modified into spine. In Euphorbia, the entire leaf with stipules are modified into spines. Spines perform function of protection.

Thus, the correct answer is 'a-iii, b-iv, c-v, d-ii.'
