2. Tiwater’s performanpresentation most likely fails to comply with the GIPS stanr because it es not sclose the: custom benchmark weights ancomponents. presence, use, anextent of leverage or rivatives. te anreasons for the change in the composite name. GIPS Provision I.4.A.31 states, \"If a custom benchmark or combination of multiple benchmarks is use the firm must sclose the benchmark components, weights anre-balancing process.\" Tiwater scloses the frequenof custom benchmark rebalancing but es not scrithe custom benchmark weights ancomponents. B is not the best answer because the Stanr require sclosure of the presence, use, anextent of leverage or rivatives only if the use of leverage or rivatives is material. C is incorrebecause the Stanr require only thfirms sclose any changes to the name of a composite. Firms are not requireto sclose the te anreasons for the composite name change. (See Section 3.11 of the reang.) 答案和之前企鹅助教讲的不同。 企鹅助教的https://class.pzacamy.com/qa/25165 答案老师，正确答案中不是这么说的 啊，“C is incorrebecause the Stanr require only thfirms sclose any changes to the name of a composite. ” 也就是“改名的，才要求披露改名的原因；没改名的不需要披露”，也就是说只要改名字，就需要披露啊？？？
请问B为什么不对？谢谢
