The animals on the left and in the middle have been sensitized to bacteria strain A, so they would not be able to mount an effective immune response against toxin from strain B. Therefore, both animals on the left and in the middle would die from the lethal dose of toxin from strain B. The animal on the right, which has not been sensitized to any bacterial strain, would not be affected and would survive.
