<em>The characteristic of skin that makes it unpleasant for most bacteria would be due to all of the conditions.</em>
Most bacteria require humid condition in order to grow and as such, the desiccated nature of the normal human skin makes it difficult for them to establish themselves and grow on it.
The pH of the skin is usually acidic due to the production of lactic acid during sweating and the activities of the normal skin bacteria. The acidic pH hinders the growth of bacteria that can potentially become pathogenic to the skin.
Also, the skin produce antimicrobial substances at low pH which hinders the growth of pathogenic bacteria.
Hence, options b, c, and d are correct.
