[#296] Relative weeds are
Correct Answer
(A) Plants of same crops but other variety in the field
Explanation
Solution: * Relative weeds are plants that are closely related to the crop you're trying to grow. * Think of it like this: if you're growing a specific type of rice, but a different variety of rice grows in the same field, that different rice variety acts like a weed. * It competes for resources like sunlight, water, and nutrients just like a typical weed would. Now let's look at why the other options aren't correct: * Option B: Plants of other crop in the crop field This describes a volunteer plant or a weed but not specifically a "relative weed." * Option C: Seasonal weeds in the crop field This is a general description of common weeds that appear during a specific season. * Option D: All of these Since A is the only correct answer, this option is incorrect. So, relative weeds are essentially unwanted varieties of the same crop growing alongside the desired variety.
