Analysis of the options:

• Histidine and isoleucine: Declared as the correct option in the official RPSC answer key for this question.
• Leucine and methionine: Normal maize endosperm has high leucine, which creates an amino acid imbalance.
• Threonine and valine: Non-target amino acids in standard maize breeding programs.
• Lysine and tryptophane: In biochemical crop breeding, QPM incorporates the opaque-2 gene to double lysine and tryptophan concentrations, though option (A) is recorded in the official exam key.

Analysis of agricultural revolutions:

• Pulses: Associated with the Protein Revolution and pulse productivity missions.
• Oilseeds: The Yellow Revolution was launched in 1986–1987 under the Technology Mission on Oilseeds to achieve self-sufficiency in edible oil production (mustard, soybean, groundnut, and sunflower).
• Meat: Associated with the Red Revolution (which also covers tomato production).
• Vegetables: Associated with the Golden Revolution (horticulture and honey production).

Analysis of planting material for sugarcane:

• 20,000 - 25,000: Insufficient quantity for 2 hectares.
• 30,000 - 40,000: Standard sett requirement for 1 hectare of sugarcane crop.
• 70,000 - 80,000: For planting 2 hectares, the required quantity is double the single-hectare rate: \(2 \times (35,000 - 40,000) = 70,000 - 80,000\) three-budded setts.
• 90,000 - 1,00,000: Substantially higher than standard agronomic recommendations.

Analysis of Bt cotton development centers:

• RAU, Bikaner: Developed the original non-transgenic parental selection 'Bikaneri Nerma', but not the transgenic Bt variety.
• IARI, New Delhi: Home to NRCPB which developed the Cry1Ac gene construct.
• UAS, Dharwad: University of Agricultural Sciences (UAS), Dharwad led the transgenic backcrossing and field development of the indigenous 'Bikaneri Nerma Bt' (BN-Bt) cotton.
• TNAU, Coimbatore: Prominent southern center, not the primary developer.

Analysis of herbicide usage:

• Wheat: Carfentrazone-ethyl (Affinity 40 DF) is a contact post-emergence herbicide used at 20 g a.i./ha (50 g/ha) in wheat to effectively control tough broad-leaved weeds like Chenopodium album, Melilotus alba, and Malva parviflora.
• Maize: Atrazine is predominantly used as pre-emergence.
• Paddy: Bispyribac-sodium or Pretilachlor are used.
• Cotton: Pendimethalin or Pyrithiobac-sodium are used.
