1) Producing acids.
2) Bactreocin production
3) By occupying the niches that the pathogens may occupy.
But the microbes cant compete with other microbes by producing vitamins and growth factors that can be utilized by the host.
Hence option E is the right answer.
Water is mostly water molecules so adding water to an acid or base reduces the concentration of ions in the solution. When an acidic solution is diluted with water the concentration of H + ions decreases and the pH of the solution increases towards 7.
