Questions: Which of the following situations involves Transgenics? A. Modifying lettuce to be frost resistant. B. Gene for human antibodies being introduced to goats. C. Human insulin being produced from bacteria. D. Creating potatoes that are toxic to beetles.

The answer is B: Gene for human antibodies being introduced to goats.

Explanation for each option: A. Modifying lettuce to be frost resistant - This involves genetic modification, but it does not necessarily involve transgenics unless the frost resistance gene comes from a different species. B. Gene for human antibodies being introduced to goats - This is a clear example of transgenics, as it involves introducing a gene from one species (human) into another species (goat). C. Human insulin being produced from bacteria - This is an example of genetic engineering, but it is not transgenics because it involves using bacteria to produce a human protein, not introducing a gene from one species into another. D. Creating potatoes that are toxic to beetles - This involves genetic modification, but it does not necessarily involve transgenics unless the gene for toxicity comes from a different species.

Summary: The situation that involves transgenics is the introduction of a gene for human antibodies into goats.
