问题如下：
Which of the following has the highest weighting to current yield?选项：
A.Greenfield assets with limited construction and demand risk B.Fully constructed brownfield assets with contracted revenues C.Greenfield assets without guarantees of demand upon completion解释：
Brownfield assets with mitigated risks (e.g., fully con- structed with contracted/regulated revenues) that are located in the most stable OECD countries have a high weighting to current yield. Greenfield assets with limited construction and demand risk have a mix of yield and capital appreciation. Greenfield projects without guarantees of demand upon completion—e.g., variable electricity prices, uncertain traffic on roads and through ports—have a high weighting to capital appreciation.
棕地（例如，已完全建成并具有合同或受监管的收入），位于最稳定的经济合作与发展组织（OECD）国家，其主要依赖于当前收益。而那些具有有限建设和需求风险的绿地资产，则是当前收益和资本增值的混合。没有完成时需求保证的绿地项目则主要依赖于资本增值。
current yield是等于annual coupon payment/market value吧？
那这道题应该怎么解析？我虽然理解解释中说绿地主要依靠增值，但是这和current yield有什么关系？
