Which of the following accurately describes a weed?

• A. A beneficial plant for ecosystems
• B. An undesirable plant that competes with crops
• C. A source of medicinal properties
• D. A cultivated plant species

Answer: (B)

A weed is accurately described as an undesirable plant that competes with crops. Weeds often grow uncontrollably and can outcompete desirable plants for resources such as sunlight, water, and nutrients, which diminishes the growth and yield of crops. They can also host pests and diseases that affect agricultural productivity. Thus, the classification of a weed primarily hinges on its negative impact on crop plants and productivity within agricultural settings. The other options do not align with this definition; they focus on beneficial aspects or cultivated plants, which are not considered weeds due to their positive roles or intentional cultivation.
