super bug is

1. pseudomonas pudita
2. bacillus anthrax
3. atreptomyces erthreus
4. mucor

The correct option is 1.
A superbug, also called multiresistant, is a bacterium that carries several resistance genes. The risk for colonisation increases if there is a lack of susceptibility (resistance) of the superbugs to the antibiotic used and high tissue penetration, as well as broad-spectrum activity against "good bacteria".
