• is correct because snow peas / mangetout (Pisum sativum var. saccharatum) have parchment-free, thin-walled flat tender pods eaten whole.
• is incorrect because presence of semi-parchment imparts fibrous stringiness.
• is also correct because snap peas (Pisum sativum var. macrocarpon) have parchment-free, thick-walled fleshy succulent pods eaten whole as green pods.
• is incorrect because parchment layers (sclerenchymatous endocarp) make pods unpalatable and fibrous.
  Note: Because edible-podded peas comprise two distinct market classes—snow peas (Option 1: parchment-free, thin-walled) and snap peas (Option 3: parchment-free, thick-walled)—NTA officially accepted both Option 1 and Option 3 ('1&3') as correct.

Desirable characteristics for white pepper production from black pepper (Piper nigrum):

• Low pericarp/seed ratio is desirable because white pepper is produced by retting or decorticating fully ripe berries to remove the mesocarp and pericarp, leaving only the inner seed. A lower pericarp-to-seed ratio indicates a thinner skin/pericarp and a plump, larger seed kernel, maximizing white pepper recovery yield.
• High pericarp/seed ratio results in excessive outer tissue loss and smaller seed recovery, which reduces processing efficiency.
• Medium pericarp/seed ratio provides sub-optimal recovery compared to low ratio varieties.
• Very high pericarp/seed ratio leads to maximum weight loss during decortication and minimal white pepper yield.
  
  Option breakdown:
• Low pericarp/seed ratio is the correct and desired attribute.
• High ratio leads to lower recovery.
• Medium ratio is not the optimal standard.
• Very high ratio gives poorest output.

Seed rate recommendations in fenugreek:

• $10-12\text{ kg/ha}$: Kasuri methi (Trigonella corniculata) has very small test-weight seeds compared to common methi, and the standard agronomic recommendation is $10-12\text{ kg/ha}$.
• $20-25\text{ kg/ha}$ is the standard seed rate for bold-seeded common methi (Trigonella foenum-graecum).
• $13-20\text{ kg/ha}$ is outside the standard agronomic recommendation.
• $6-8\text{ kg/ha}$ provides inadequate plant stand.
  
  Option breakdown:
• $10-12\text{ kg/ha}$ is correct for Kasuri type.
• $20-25\text{ kg/ha}$ is for common methi.
• Incorrect range.
• Too low.
