Answer: (A) Tobacco

Tobacco was the first transgenic (genetically modified) crop, developed in the early 1980s by researchers who inserted antibiotic-resistance genes into tobacco plants using Agrobacterium tumefaciens as a vector. This pioneering work opened the door to commercial GM crops like Bt cotton and Golden Rice.
