Answer 1

Step 1: Agropyron repens, Cyperus rotundus and Cynodon dactylon are all classic rhizomatous weeds.
Step 2: Cirsium arvense spreads mainly via its creeping root system and seeds, not true rhizomes.
Step 3: So the rhizome-propagated weeds are A, B and D only.
Correct option: (A), (B) and (D) only.
