Explanation
In the field of biology and, more specifically, in the study of pathogens, a 'portal of entry' refers to the method or route by which a pathogen enters its host organism. This portal may refer to physical openings in the host (e.g. mouth, eyes, nose, injuries, etc) or other physiological routes (e.g through ingested food). The options A and B describe other characteristics of microorganisms, but they're not relevant to the specific term 'portal of entry'. Option D, which mentions the movement of an organism, is more related to the term 'modes of transmission' than 'portal of entry'.
