Which of these frogs is one of the most poisonous?

The golden poison frog ('Phyllobates terribilis') is the most poisonous species of frog endemic to the Pacific coast of Colombia. The optimal habitat of 'P. terribilis' is the rainforest with high rain rates (5 m or more per year), altitudes between 100 and 200 m, temperatures of at least 26 °C, and relative humidity of 80–90%. In the wild, 'P. terribilis' is a social animal, living in groups of up to six individuals; however, captive 'P. terribilis' specimens can live in much larger groups. These frogs are often considered innocuous due to their small size and bright colours, but wild frogs are lethally toxic.
