Match List - I with List - II and choose the correct answer.

List - I	List - II
(a) Protoplast fusion	(i) Totipotency
(b) Plant tissue culture	(ii) Pomato
(c) Meristem culture	(iii) Somoclones
(d) Micropropagation	(iv) Virus free plants

The correct option is a - (ii) b - (i) c - (iv) d - (iii).

Let us break down the logical matching between List - I and List - II:

1. (a) Protoplast fusion matches with (ii) Pomato:
Protoplast fusion is a technique in biotechnology where protoplasts (plant cells with their cell walls removed) from two different plant species are fused together to form a somatic hybrid. A classic example of this is the "Pomato", which is created by fusing protoplasts from potato and tomato plants.

2. (b) Plant tissue culture matches with (i) Totipotency:
Plant tissue culture relies on the biological property of totipotency. Totipotency is the ability of a single plant cell or tissue (explant) to regenerate into a whole new plant when grown in suitable nutrient media under sterile laboratory conditions.

3. (c) Meristem culture matches with (iv) Virus free plants:
Even in a virus-infected plant, the apical and axillary meristems (the actively dividing shoot tips) are generally free of viruses. Culturing these meristem tissues in vitro is a standard method used to recover healthy, virus-free clones from infected parent plants.

4. (d) Micropropagation matches with (iii) Somoclones:
Micropropagation is the technique of rapidly multiplying plant material to produce a large number of progeny plants using tissue culture methods. Because these plants are produced vegetatively from a single explant, they are genetically identical to each other and to the parent plant, and are thus referred to as somoclones.
