EXPLANATION
Structural & Numerical Chromosomal Aberration
- Haploid Chromosome Numbers ($n$) in Major Field Crops:
- Hordeum vulgare (Barley): Diploid species with $2n = 2x = 14$; haploid chromosome number is $n = 7$ $\rightarrow$ (II)
- Chickpea (Cicer arietinum): Diploid pulse with $2n = 2x = 16$; haploid chromosome number is $n = 8$ $\rightarrow$ (I)
- Sunflower (Helianthus annuus): Diploid oilseed with $2n = 2x = 34$; haploid chromosome number is $n = 17$ $\rightarrow$ (IV)
- Rice (Oryza sativa): Diploid cereal with $2n = 2x = 24$; haploid chromosome number is $n = 12$ $\rightarrow$ (III)
- Systematic Match: (A)-(II), (B)-(I), (C)-(IV), (D)-(III) corresponds to Option 3.
Correct option: (3) (A) - (II), (B) - (1), (C) - (IV), (D) - (ttl)
