• Production of Omega-3 Enriched Designer Eggs:
• Avian lipid metabolism is unique because unlike ruminants (where rumen biohydrogenation saturates dietary lipids), laying hens directly absorb dietary fatty acids and incorporate them intact into hepatic very-low-density lipoproteins (VLDL-yolk).
• Dietary inclusion of marine fish oils, fish meal, or microalgal biomass rich in long-chain polyunsaturated fatty acids (EPA, DHA) directly and markedly elevates the $\omega-3$ fatty acid content of egg yolk lipids.
• nalysis:
• Both (A) and (R) are true, and (R) provides the physiological explanation for (A). Hence, Option 1 is correct.

• Wool Processing - Carding and Combing:
• In the worsted wool manufacturing system, wool fibers pass through circular or rectilinear comb machinery:
• Tops: The desirable long, straight, parallel fibers retained and wound into continuous slivers for spinning into fine worsted yarn.
• Noils: The short, tangled, irregular fibers and knotty neps combed out as a secondary product, subsequently used in woollen blends and felts.
• nalysis:
• (Noils): Correct term for short combed-out fibers.

Correct option: (2) Noils

• Chemical Removal of Vegetable Matter from Wool:
• Raw greasy fleece frequently contains heavy vegetable contamination (burrs, seeds, straw, twigs).
• Carbonization:
• Wool is immersed in a dilute mineral acid solution ($5-7\%\text{ H}_2\text{SO}_4$), squeezed, and baked in a carbonizing oven at $105-110^\circ\text{C}$.
• The acid dehydrates and chars the cellulosic vegetable matter into brittle, friable carbon without damaging the acid-resistant wool keratin.
• Subsequent fluted crush rollers pulverize the charred carbon into dust, which is blown away.
• nalysis:
• (Carbonization): Correct.

Correct option: (1) Carbonization
