In wild-type Arabidopsis thaliana, the four types of floral organs (sepal, petal, stamen, carpel) are arranged in concentric whorls from outside to inside. With reference to the ABC model of floral organ patterning, match the homeotic mutants in Group 1 with their respective arrangements of organs in the four whorls given in Group 2.
| Group 1 | Group 2 |
| (P) A class mutants | (i)sepal, sepal, carpel, carpel |
| (Q) B class mutants | (ii) sepal, petal, petal, sepal |
| (R) C class mutants | (iii) carpel, stamen, stamen, carpel |
| | (iv) sepal, sepal, petal, petal |
