Quizplus · Accepted Answer

If a valley glacier is lengthening (extending its terminus downslope) over a period of many years, it means that more snow and ice are accumulating at the upper end of the glacier than are melting and flowing away at the lower end. This suggests that accumulation exceeds wastage, making option B the correct choice.
