Isobaric surfaces, also known as pressure surfaces, represent a constant pressure at a certain altitude. In warm, less-dense air, pressure decreases more quickly with altitude, causing the isobaric surfaces to be at higher altitudes. In cold, more-dense air, pressure decreases more slowly with altitude, causing isobaric surfaces to be at lower altitudes. Therefore, the answer is B.
