The sharp wind shift across a short distance and a marked change in temperature and humidity indicate the presence of a frontal boundary, where two different air masses are meeting. This is represented on a surface weather map by a line with symbols indicating the type of front (cold, warm, occluded, or stationary). Therefore, option B, a front, is the correct choice.
