JEE Main Chemistry question

Following solutions at the same temperature will be isotonic:

(A)3.42 g of cane sugar in one litre water and 0.18 g of glucose in one litre water
(B)3.42 g of cane sugar in one litre water and 0.18 g of glucose in 0.1 litre waterCorrect
(C)3.42 g of cane sugar in one litre water and 0.585 g of NaCl in one litre water
(D)3.42 g of cane sugar in one litre water and 1.17 g of NaCl in one litre water

Answer: (B)

Solution

Cane sugar (342 g/mol): mol/L. In (B), glucose (180 g/mol): mol/L — equal molarity and both non-electrolytes (), so isotonic. In (A) the glucose
