Concept:
This question is based on matching dyeing and finishing concepts with their respective machines or theoretical models used in textile wet processing.
Step 1: Understand each term.
• Static Pore theory → relates to dye penetration and diffusion behavior
• 6 kg quality → refers to batch dyeing classification for small lots
• Overfeed % → relates to stenter and fabric relaxation control
• Twin U-Jet → jet dyeing machine type
Step 2: Match logically.
• Static Pore theory → Dyeing mechanism (II)
• 6 kg quality → Clip stenter or small batch handling (I)
• Overfeed % → Stenter control system (VI)
• Twin U-Jet → Jet dyeing system (II or related dyeing mechanism)
Step 3: Final correct mapping.
\[
A-V,\; B-I,\; C-VI,\; D-II
\]
Step 4: Final answer.
\[
\boxed{\text{A-V, B-I, C-VI, D-II}}
\]
Thus,
\[
\boxed{\text{Option (C) is correct.}}
\]
