Which of the following crop traits most directly corresponds to Bt engineering and which to glyphosate resistance?

• A. Bt engineering → sterilization of seeds to prevent replanting; Glyphosate resistance → mandatory use of organic weed control practices.
• B. Bt engineering → drought resistance achieved via root modification; Glyphosate resistance → enhanced sugar content for sweeter crops.
• C. Bt engineering → internal production of insecticidal proteins targeting caterpillars; Glyphosate resistance → tolerance to a broad‑spectrum herbicide allowing weed control without crop damage.
• D. Bt engineering → enhanced vitamin A synthesis for human nutrition; Glyphosate resistance → ability to photosynthesize using glyphosate as an alternative source of carbon.

Answer: (C)
