• A. Lolium perene
• B. Zoysia japonica
• C. Paspalum vaginatum

Warm-season: Zoysia, Bermuda, St. Augustine, Paspalum, Buffalograss. Best in warmer climates.

Answer 1

The Correct Option is A

Step 1: Zoysia, Paspalum and Buchloe are all warm-season grasses adapted to hot climates.
Step 2: Lolium perenne grows best in cool temperate conditions (about 15-24°C).
Step 3: This makes it the cool-season lawn grass among the options.
Step 4: Correct option: \( \boxed{\text{Lolium perene}} \).
