Question & Answer
Choose the Best Answer
Editing the genome of a plant to enhance drought resistance
Using traditional breeding techniques to develop a new crop variety
Adding fertilizers to improve soil quality
Introducing a new species to an ecosystem
Understanding the Answer
Let's break down why this is correct
CRISPR-Cas9 is a tool that cuts DNA at a chosen spot and lets scientists add or remove genes. Other options are incorrect because Traditional breeding changes genes over many generations, not by cutting DNA; Adding fertilizers improves soil, not the plant’s genes.
