• B. Lens culinaris
• C. Glycine max
• D. Abrus precatorius

Answer 1

The correct option is D

Abrus precatorius

Abrus precatorius, known commonly as jequirity bean, rosary pea, or crab-eye seed is a herbaceous flowering plant in the bean family Fabaceae. It is a slender, perennial climber with long, pinnate-leafleted leaves that twines around trees, shrubs, and hedges. It is much valued in nativejewelry for their bright coloration. Most beans are black and red, reminiscent of a ladybug, though other colors exist. Jewelry-making with jequirity seeds is somewhat hazardous. So, the correct answer is 'Abrus precatorius'.
