Which of the following statements about ESG indices is most accurate? ESG scores used for weightings tilts:
选项：
A.must be data-based only.
B.must be ratings-based only.
C.can be either data-based or ratings-based.
解释：
C is correct because "these ETFs follow the underlying index or basket construction in a rules-based fashion. These can be thematic, namely investing only in certain sectors, or tilt weightings based on ESG scores, as described earlier. These scores maybe be data-based (for example, carbon emissions) or ratings-based (for example, on a provider’s ratings), or a mix of the two. There continue to be debates as to how well these ETFs capture potential ESG factors."
