A Correct answer
Explanation

bar gene confers herbicide resistance (4). vip3A is for insect resistance (3). The gene for vitamin A (often phytoene synthase) is not listed correctly as R. gsh-II is for heavy metal tolerance (1). The provided match A is the most logical fit based on standard biotechnology knowledge.
