Name the plant which commonly causes bloat.

Answer: Option A

Clover plant commonly causes bloat.
They are small annual, biennial, or short-lived perennial herbaceous plants, typically growing up to 30 cm tall. The leaves are trifoliate with stipules adnate to the leaf-stalk, and heads or dense spikes of small red, purple, white, or yellow flowers; the small, few-seeded pods are enclosed in the calyx.
Clover is foraged by wildlife, including bears, game animals, and birds. Native Americans ate the plants raw and cooked, drying and smoking the roots. It causes bloating in cattle as well as humans.
