|---|---|---|---|
| A | Dicliny Dicliny | I | Protogyny and Protandry Protogyny and Protandry |
| B | Dichogamy Dichogamy | II | Monoecy and Dioecy Monoecy and Dioecy |
| C | Self incompatibility Self incompatibility | III | Genetic, cytoplasmic, cytoplasmic genetic Genetic, cytoplasmic, cytoplasmic genetic |
| D | Male sterility Male sterility | IV | Sporophytic and gametophytic Sporophytic and gametophytic |
- Dicliny (Unisexuality) $\rightarrow$ (II) Monoecy and Dioecy: Flowers are structurally unisexual (either staminate or pistillate), occurring on the same plant (monoecy) or separate plants (dioecy).
- Dichogamy $\rightarrow$ (I) Protogyny and Protandry: Temporal separation in sexual maturation; anthers shed pollen before stigmas become receptive (protandry) or stigmas mature first (protogyny).
- Self-incompatibility $\rightarrow$ (IV) Sporophytic and Gametophytic: Physiological barrier preventing self-fertilization, genetically governed by the $S$-phenotype of pollen parent (sporophytic SI) or pollen grain genotype (gametophytic SI).
- Male Sterility $\rightarrow$ (III) Genetic, Cytoplasmic, Cytoplasmic Genetic: Non-functional pollen controlled by nuclear genes (GMS), mitochondrial genes (CMS), or nuclear-cytoplasmic restoration systems (CGMS).
- Correct Combination: (A)-(II), (B)-(I), (C)-(IV), (D)-(III), matching Option 4.
Correct option: (4) -(A)- (I), (BY (1), (CH(IV), (D)-(1ID)
