Four different mutant lines showing similar phenotype were identified from a genetic screen. When genetic crosses among these mutants were carried out, the first mutant was found to complement the second, third and fourth mutant lines. However, no other complementation groups do the four mutant lines belongs to?

Identify the correct match of the modes of regeneration (column I) with their definition (column II)

Column I	Column II
A. Stem cell-mediated regeneration	i. Through the re-patterning of existing tissues. There is often little new growth but rather cell death and a change in cell type (i.e., transdifferentiation into a different cell fate). This results in a rescaling of the whole organism as well as regeneration of the missing part.
B. Epimorphosis	ii. The differentiated cells divide but maintain their differentiated functions. The new cells do not come from stem cells, nor do they come from the dedifferentiation of adult cells.
C. Morphallaxis	iii. Adult structures can undergo dedifferentiation to form a relatively undifferentiated mass of cells (a blastema) that then redifferentiates during morphogenesis of the new structure.
D. Compensatory regeneration	iv. Stem cells allow an organism to regrow certain organs or tissues that have been lost.
