Electrochemical  cells are represented as-
straight M space vertical line space straight M subscript straight c 1 end subscript to the power of plus vertical line vertical line space straight M subscript straight c 2 end subscript to the power of plus vertical line straight M where space straight c subscript 1 space and space straight c subscript 2 space are space ooncentrations space of space the space electrolyte space of space the space same space metal space whose space electrodes space are space used. This space cell space wil space work space only space when space straight c subscript 2 greater than straight c subscript 1
So option(i) is correct.
