However, on 2nd MB PM, 3-cusp type(H-shape) doesn't exist L cusp, only ML and DL cusp (even the ML is located Centered); on 2-cusp type( U-shape), L cusp is either closed to M or Centered. So in this case, we shouldn't consider B as a corrected answer?

	7F 小甜瓜瓜（蝦皮：melon 高一下 (2022/06/12) （B) "Sometimes, however, the mesial and distal marginal ridges may converge symmetrically toward the lingual cusp in such a way that the occlusal table (surface) is nearly an equilateral triangle with the base made up of the buccal cusp ridges, and the apex is the lingual cusp tip as illustrated in red on Figure 4-24. " 課本有一段提到下顎第一小臼齒有時會等腰三角形般的咬合面，lingual cusp相對至中。檢舉
