Q.A leaf in which the veins and veinlets are arranged in an irregular, net-like pattern over the lamina shows:

When the veins of a leaf form a branching, net-like pattern over the whole lamina, the venation is called reticulate -- the pattern typical of dicotyledons, e.g. China rose and Peepal. Parallel venation (a), by contrast, has veins running alongside one another without forming a net, as in most monocotyledons such as grasses and banana. Radial symmetry (c) and valvate aestivation (d) describe the arrangement of floral parts, not of leaf veins at all, so they do not fit the description given.

Match the described vein pattern (net-like vs parallel) to its named term, and rule out the two floral terms that describe an unrelated structure (the flower, not the leaf).

• Confusing reticulate (net-like, dicot) venation with parallel (dicot vs monocot mix-up) venation.
• Picking a floral term such as 'aestivation' because it sounds technical, without noticing the question is about a leaf, not a flower.
