Arrange the steps of somatic hybridization in correct chronological order:
I. Protoplast fusion using electric shock (electrofusion) or chemical treatment.
II. The removal of the cell wall of one cell of each type of plant using cellulase enzyme to produce a somatic cell called a protoplast
III. The formation of the cell wall induced using hormones
IV. The cells are then grown into calluses which then are further grown to plantlets and finally to a full plant, known as a somatic hybrid.
1. I → II → III → IV
2. I → II → IV → III
3. II → I → III → IV
4. II → I → IV → III
