Relative weeds are

Answer: Option A

* 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.
