To determine the most likely weather as Sandy walked home, we need to consider the information provided. We know that it was nice and warm in the morning when she walked to school, but a cold front was moving through later in the day.

Based on this information, it is reasonable to assume that the weather would have become cooler by the time Sandy walked home. Cold fronts usually bring cooler temperatures, so option B) cooler is the most likely answer in this scenario.
