Which of the following weeds typically matures and dies within a year?

Annual weeds are characterized by their life cycle, which consists of completing their maturation and reproductive stages within a single growing season. These weeds germinate, grow, flower, and produce seeds all within one year, after which they die. This rapid life cycle allows them to quickly exploit favorable growing conditions and can result in dense populations if not managed effectively.

In contrast, perennial weeds live for multiple years and can regrow year after year, while biennial weeds typically take two years to complete their life cycle, developing in the first year and flowering in the second. The term "deciduous" relates to plants that shed their leaves seasonally, and is not applicable in this context of weed classification. Thus, annual weeds are the right choice as they align with the question about plants that mature and die within a single year.
