The correct option is B Abrus precatorius
Abrus precatorius is a slender, perennial climber, that twines around trees, shrubs, and hedges. It is a legume with alternate compound leaves, 2 to 5 inches long, with 5 to 15 pairs of oblong leaflets. A key characteristic in identifying rosary pea is the lack of a terminal leaflet on the compound leaves. The plant is best known for its seeds, which are used as beads in native jewelry, as well as in percussion instruments. Necklaces and other ornaments made from the seeds are worn by both children and adults. These seeds are toxic due to the presence of abrin. Formerly Indians used these seeds to weigh gold using a measure called as 'Ratti'.
