Which of the following is NOT a weed life cycle type?

• A. Annual
• B. Biennial
• C. Transient
• D. Perennial

Answer: (C)

Weed life cycles are categorized by how long they live and reproduce. Annuals complete their entire life cycle in one growing season, biennials need two years (usually growing vegetatively the first year and flowering the second), and perennials live for multiple years and can regrow each season. Transient isn’t used as a standard life cycle category in weed biology, so it isn’t a recognized life cycle type. That’s why the other terms fit as life cycle patterns, while transient does not. For context, examples help: annuals like common sunflower complete in one year, biennials like foxglove require two years, and perennials like dandelion persist and regrow over many years.
