Carbohydrates and lipids — practice question

Teixobactin, an antibiotic, was found in January 2015. It is lethal to some bacteria, including Staphylococcus and Mycobacterium. Most antibiotics act by attaching to proteins. Teixobactin attaches to lipids that are involved in the formation of bacterial cell walls. As a result, bacteria are unlikely to gain resistance to teixobactin rapidly. Which statements account for the fact that bacteria are unlikely to develop resistance to teixobactin quickly?
