A cutting that is usually made from large leaf plant with the veins split is
A
split-vein cutting
B
leaf petiole cutting
C
terminal tip cutting
D
tissue propagation
Explanation: 

Detailed explanation-1: -Make cuts on several prominent veins on the underside of the leaf (Figure 3). Lay the cutting, lower side down, on the medium. If the leaf curls up, hold it in place by covering the margins with rooting medium. New plants will form at each cut.

Detailed explanation-2: -Leaf Vein Cuttings: take a leaf and cut it into sections, each section with a vein. The bottom portion of the vein can then be pressed into the propagation medium with the leaf portion sticking up to root just like a leaf cutting. In this manner one leaf can produce up to a dozen new plants.

Detailed explanation-3: -The three types of hardwood cuttings are straight, mallet, and heel (Figure 3). A straight cutting is the most commonly used stem cutting. Mallet and heel cuttings are used for plants that might otherwise be more difficult to root.

Detailed explanation-4: -Examples of plants that can be propagated by leaf-petiole cuttings include African violet, peperomia, episcia, hoya, and sedum.

Detailed explanation-5: -Once your plant its out of its old pot, place the houseplant on a secure surface and use your fingers to loosen the root ball. Then, take a a sharp knife and cut the plant into sections. Make sure each section has a healthy section of roots and a few leaves. Replant divisions as soon as possible in fresh potting mix.
