Answer :
The correct answer to the question is:
4. The ability of plants to naturally resist herbicide applications
Explanation:
Herbicide tolerance in plants refers to the ability of certain plants to withstand the effects of herbicides, which are chemicals used to control or kill unwanted vegetation. This tolerance is usually achieved through genetic modifications that allow the plant to survive herbicide exposure while the targeted weeds are eliminated. As a result, herbicide-tolerant plants can grow and thrive in fields treated with herbicides, providing benefits such as weed control and increased crop yields.
This trait is particularly valuable in agriculture, as it allows farmers to effectively manage weeds without causing harm to the desired crop. By understanding and utilizing herbicide tolerance in plants, farmers can enhance the efficiency and sustainability of their agricultural practices.
